It's just a 75mm Sherman Dozer. That's just a cover over the end of the barrel, not a muzzle brake. You can also see that the barrel is too short, as well as the protrusions on original M34A1 gun mount. Those protrusions were removed in Firefly conversions.

It's much more inefficient to store one piece ammo under the turret floor. You need a lot of space in the turret to transfer it to a ready rack. The western style storage in the rear of the turret with blow out panels is far and above superior design. It makes the entire tank more survivable not just the crew.

I am a great "what if" fan and "what if we stood up to Hitler earlier" is one of my thought experiments. Like you,I find 1930s tank design fascinating and as you say its easy to denigrate it with the benefit of hindsight and assuming 1940s tech. I am probably going to have a go sculpting an A7E3 in Blender for our 3D resin printer!!

It is not impossible, as a large number of immigrants left the former Russian Empire after its collapse and a tremendous number of people were involved in designing the Sherman tank and its various components. Here is one engineer called Timoshenko who emigrated to the US, although the article doesn't mention his relationship to the marshal or involvement with the Sherman tank. http://auditori-um.ru/personalii/s-p-timoshenko-russkij-osnovatel-amerikanskoj-shkoly-texnicheskoj-mexaniki/<br /><br />Peterhttps://www.blogger.com/profile/09622237223229485503noreply@blogger.comtag:blogger.com,1999:blog-5030145265861917845.post-32140424662303978752024-01-20T15:21:54.908-05:002024-01-20T15:21:54.908-05:00A not related question but I like to know more abo...A not related question but I like to know more about this quote aperantly mentioned in an interview of former Soviet tank veteran saying this ...please <br />" Did you know that one of the designers of the Sherman was a Russian engineer named Timoshenko?

For instance, the prototype of the Leopard 2 weighed 50.5 tons, the first production tank weighed 55 tons, and modern Leopard 2 tanks weigh 65 tons and continue to grow. This weight gain is not a desirable characteristic of the Main Battle Tank class, but a significant problem. "<br /><br />I would dispute this a bit---the MBTs of today over 50 tons require support services that may not be available in any prolonged shooting war. I recall a comment made on Quora where a British soldier said he saw a Chieftain trying to cross a bridge and the bridge collapsed under the tank's weight. Ergo, these 60 and 70 + ton tanks will require engineers always at-hand to reinforce bridges for movements.<br /><br />Will such support always be available? I question that. I recall similar criticisms being made by military observers about Western armies always seeming to assume that they will enjoy air superiority, or have ample logistical support, or engineer support. In effect, that the next war would be like WWII, where US-supplied armies always were lavishly supported. However, the US has neglected its own manufacturing base for the past 40-plus years and may no longer be any 'arsenal of democracy'. Recent criticisms also maintain the US may be facing a manpower problem on top of that.<br /><br />With that in mind, having a 50-ton weight limit for a MBT, the limit that most bridges can support, may be the wisest course.Stewart Millenhttps://www.blogger.com/profile/01261690405884935161noreply@blogger.comtag:blogger.com,1999:blog-5030145265861917845.post-48021230410815323962023-09-15T10:56:55.190-04:002023-09-15T10:56:55.190-04:00It's a pity.

Although these two springs are sometimes not clearly distinguished, they actually have completely different shapes. This suspension is basically the same as a clothespin.<br />On the one hand, Sahariano's choice is certainly interesting, since they already had a true torsion bar on their L6 light tank. Apparently they wanted something that wasn't a torsion bar or a Christie.Tanakahttps://www.blogger.com/profile/03766137590879790167noreply@blogger.comtag:blogger.com,1999:blog-5030145265861917845.post-29789098022434203452023-08-26T14:59:39.581-04:002023-08-26T14:59:39.581-04:00The S-54 in a T-34 was definitely a viable upgrade...The S-54 in a T-34 was definitely a viable upgrade and I assume that the KV-1S would also have been able to take it without an issue, but then you would have to juggle a new type of round with the same caliber as an old one.
