South Haven, MI, is about 40 minutes up the road from us and we’ve been there a number of times over the years. On a number of occasions we’ve driven by American Legion Post 49 and seen the M60A3 tank sitting overlooking the river. We were up there recently and I snapped a few pictures in order to assemble a post about it.
The tank is a M60A3 serial number 7582 and was overhauled at Anniston Army Depot in October 1988.
The “Tank, Combat, Full Tracked: 105mm Gun, M60” was officially adopted in March 1959 and was an evolutionary design from the M48A2 Patton though never officially considered as part of the Patton family.
The M60 tanks served as the main battle tank during the cold war with 15,000 being produced. It was first put into operational use in Europe in 1960. Chrysler started production in 1959 and then the Detroit Arsenal Tank Plat produced them from 1960-1983.
Over it’s design life, there were many upgrades as the Americans and Soviets tried to “one up” each other in terms of capabilities. M60: 1959-1962, M60A1: 1962-1980, M60A2: 1973-1975 and then the M60A3 from 1978-1983. Note there was a modernization program and one point that upgraded 5,400 older tanks to the M60A3 variant that ended in 1990.
The M60 was eventually replaced by the M1 Abrams. The US retired the M60 from front-line use after Operation Desert Storm (August 1990-February 1991). The last tanks were retired from the National Guard in 1997. The M60 still sees use in many other countries including Egypt, Turkey and Saudi Arabia.
I am not going to cover all of the history and design changes. Click here for a good Wikipedia post with that info. Instead, I am just going to list some stats I found interesting about the M60A3 specifically.

Summary
A big thank you to the Post setting up the tank for people to see and providing the background placard.
If you are travelling through South Haven, MI, it’s worth a quick stop the the American Legion Post to see the M60A3.

As I have written in the past, I am always fascinated my old military equipment located at American Legion Posts, VFWs, cemeteries and so forth. My wife and I have driven on US-131 a number of times over the years and seen a M4 Sherman tank right by the road but have never had the time to stop and take photos until October 2022. We were on our way home and had time to stop and take a few quick photos. Now, weeks later, I did a bit of research and compiled this post.
The tank is a static display for American Legion Post 264 in Mancelona, MI located on the corner of US-131 and State Street in downtown Mancelona – if you are headed North, it’s on the the right hand side of the road just before the intersection.
The tank is a M4A3 Sherman serial number 11755 with a 75mm cannon with a small hatch and dry storage. The smaller hatches were an earlier production design and many were kept in the US for training purposes and did not see battle.
Dry storage models had ammunition racks mounted on vulnerable positions and the rounds could catch fire. Later “wet storage” models moved the racks to the floor in less vulnerable positions and protected them with sealed chambers filled with water and anti-freeze to slow the progression of fire and allow the crew a few more seconds to escape.
The Details
To be honest, I had no idea how many variants to the M4 Sherman were made – it’s stunning actually. This Wikipedia page gives info on the tank in general and this one lists info on variants. I thought this would be a quick post to write but every time I pulled back a layer and got more details that then led to more details. I had to then dig specifically on the tank to read what others had written about it.
So here is the info I could sort out:
Model: M4A3 small hatch dry storage
Maker: Ford
Where: Highland Park Plant
When: February 1943
Production: It was one of 1,690 small hatch dry storage M4A3 Shermans made by Ford between June 1942 and September 1943. This variant had the lowest production numbers.
Serial Number: 11755
US Registration: 3053910
B&R Rebuild Stamp: 579
Engine: Ford GAA V-8 500HP – that engine is really interesting – it’s an all aluminum 1,100 cubic inch 32 valve dual overhead cam 60 degree liquid cooled engine. Everything was geared – no belts or chains – so it was actually very reliable. The design is amazing in my honest opinion.
Transmission: Synchromesh with 5 speed forward and one reverse
Max road level sustained speed: 26 mph – I got stats ranging from 21 to 30 mph on this one)
Fuel type: Gasoline, at least 80 octane
Fuel Capacity: 174 gallons
Range: From TM9-759, the manual reports 110 miles cross country or 155 miles on the highway. Note that means it’s not even getting a gallon per mile in terms of fuel economy.
Suspension: Vertical volute spring suspension (VVSS) with three bogies per side and two wheels per bogie
Track: This tanks has the T48 track with rubber chevrons – 16.56″ wide and makes contact for 147″
Main Cannon: 75 mm (97 rounds carried)
Integral machine gun: Two .30 cal M1919A4 – one in the ball mount on the right side of the hull and one coaxial to the main 75mm cannon. (4,750 rounds carried)
Secondary machine gun on the turret: .50 Browning M2 (300 rounds carried)
Mortar: 2″ M3 mortar for smoke (12 rounds carried)
Small arms ammunition: 600 rounds of .45 ACP and
Weight: 30.3 tons
Length: 19’2″
Width: 8’7″
Height: 9′
Crew: 5
Okay, I am a gear head. The more I read about the Ford GAA engine, the more fascinated I got. Displacing 1,000 cubic inches or 18 liters, it remains the largest V8 gas engine Ford has made and it made more than 28,000 of them. It’s estimated that only 500-1,000 still exist and they are sometimes found in competition pulling tractors. Here’s a video of one running on a test platform in 2019:
Here are pages with more info just on the GAA engine:
There is a nearby park with a lot that we left our van at. We then came up on the tank from behind. The American Legion post did a nice job painting it. It’s always nice to see history preserved.
One of the things I noticed right away was that the rubber treads were in remarkably good shape. On some tanks they are worn down next to nothing. The folding blanket rack on the back is down.
Close up of the rear left side idler wheel. You can see a grease fitting at the 10 o’clock position.
This is a photo of the rear bogie and two wheels. The Sherman M4A3 had three bogies on each side as part of its Vertical volute spring suspension (VVSS) with three bogies per side and two wheels per bogie. The bogie is the vertical part that the two wheels connect to.
Just forward of the “American Legion” signage looks like a sign board with more text on it. That’s actually additional armor welded onto the hull.
The hatch in the turret is a pistol port. You don’t see those on modern tanks 🙂 General Steel, who made the turret, stopped casting turrets with pistol ports in May of 1943 and any with them were welded shut.
The big upside down U is a lifting eye. The hatch behind it is a cover to the grouser compartment.
This is for the blanket rolls and could have held cleaning rods, etc.
The sun and that pine tree were in just the wrong place at the wrong time so I have a ton of shadows but figured I would include the photo regardless. You can see the elaborate front sprocket.
You can see the rifling in the barrel of the 75mm cannon. 24 grooves with a 1:25.59 right hand twist. The coaxial .30 cal machine gun would have poked out of the hole to the right of the cannon. Note, the cannon is resting in it’s “travel lock”.
This shows the travel lock a little bit better. At some point – presumably during the B&R rebuild – it was upgraded to the post war single locking arm model. In WWII it would have had two “fingers” – one on each side of the barrel – that would curl around and hold it.
Looking at the front cast nose section of the tank,
7411 was cast and the -107 was stamped.
The protruding armor on the side of the turret and the sides of the hull is known as “applique armor”. It was welded in place to compensate for sections of the casting that needed to be thinner.
This is the best photo I have of the applique armor welded to the turret. The casting’s armor was thinned by 2″ internally to make room for the gunner’s controls. It’s actually two plates welded together and to the hull to compensate for the curvature of the turret.
This is the only partial close up I have of the Ford front sprocket. It’s really eye catching and unique. One of the websites mentioned that there were so many field repairs going on that it wasn’t surprising to find parts from one type of Sherman on another.
Firestone showing their brand! You can see a grease fitting as well. The lubrication guides to the Shermans are incredibly elaborate – there were many, many grease points as you can well imagine trying to keep a 30 ton
More applique armor.
A view up at the turret.
This is the exhaust deflector.
I turned around and snapped one more photo of the old tank guarding the road,
Videos of restored M4A3 Sherman tanks
When I see a piece of history, I always wonder what they looked like when they were actually running / in use. Fortunately, there are many videos of restored tanks that you can watch and here are two:
This one has some interesting coverage of the “top 10 variants” containing narration, stills and original footage:
For More Information
Folks, there is just so much history relating to the Sherman tanks that there is now way I can capture it. Below are links where you can find out a ton more:
First off, specific to the Mancelona tank, L&P Hannah took a ton of photos of it in 2014 and still have them posted online. The paint had not been refreshed at that point but what is cool is that the photographer took many photos from many angles – way more and better photos than mine. Click here to open a new tab to go to their page.
This page hosted in France has a lot of info on Ford M4A3 variants.
A gentleman named David D Jackson has assembled an amazing tribute page to the American Automobile Industry in WWII and he provides photos and a wealth of info – click here to open a tab.
This page contains a wealth of statistics on Shermans including things like armor thickness, depth of water fording, etc. It’s a treasure trove of info and you have to scroll down to the M4A3 section, Click here.
The above links reflect massive efforts by their curators to capture history before it is lost. I couldn’t have written this post without their shared works.
Summary
It was pretty neat to stop and see the tank I wish I had a ladder or something to get more angles plus I wish I took more photos but you get the general idea. I learned quite a bit while researching this post and only scratched the surface, which is why I listed all of the additional resources above.
If you are on US-131 going through Mancelona, it’s definitely worth the stop. Finally and perhaps most importantly, kudos to the members of American Legion Post 264 for keeping the tank in such good shape and sharing history with us.
