Greetings- Just curious if anyone has a source for the number of Cromwell and Churchill tanks that were produced with the 6 Pdr and 75mm guns. I know both were manufactured with both guns, but I can't find figures that show how many of which.
Thanks for any help you can give!!!

Found this on the Cromwell tank

I believe there might be some confusion on what is a Cromwell 6-pdr and what is a Cromwell 75mm, as 6-pdr guns were converted to fire US 75mm ammunition. The 75mm was problematic, which is why the 17-pdr was designed, but also why the British continued to use the 6-pdr after the war. I suspect the numbers of "75mm" could be misleading, if the MOD was recording ammunition rather than guns. I could be completely confused in the first place also, but this is my understanding of it.

? How did they do that?

Be sure, as the 6Pdr was 57mm.

I'm definitely not sure, I'll try and find the source on this where I read it.

They bored out the barrels to 75mm - the case sizes of the two rounds were very similar, so they were able to modify the breech of the 6 pounder as well, converting the gun to 75mm. This was done primarily because the 6 pounder had a high explosive shell that was inadequate in use against infantry.

I guess they could not use a high velocity rounds in the English 57mm guns.
T-34 had their high velocity 57mm in a variant of the T-34, only effective against armor though.
They penetrated much more armor than the ordinary 76mm rounds they had.

The T-34/57 was not a particularly successful variant of the T-34, in that they only built 10 (yes, ten) of them and all were lost in combat by the end of 1941.

According to Fletcher and Harley ("Cromwell Cruiser Tank 1942-1950) every Cromwell fielded in the war was either a 57mm reamed to 75mm (75,, Mk V), or a 95mm (95mm Mk I). Zero 6pdr's went to war, which was a waste because there was a sabot round (APDS) available even in those days (D-Day) that could penetrate Tiger 1 front armor at up to 1,500m.

The Crusader Mk III was armed with the 6 pdr, and saw action beginning in late 1942. The design wasn't optimal, since the turret was sized for the 2 pdr, and putting the larger gun into it required the turret crew to be reduced by one, with the Tank Commander doubling as loader.

Fixed.

THIS VEHICLE: is a Crusader Mark III, the first version to be armed with a 57mm six-pounder gun, in place of the 40mm two-pounder gun in Crusader Marks I and II. The first Crusader III was delivered in May 1942. Crusader IIIs were landed first in Algeria on 13 November 1942, but deleted from service upon conclusion of the campaign in Tunisia in May 1943, although some vehicles remained in use as tractors or carriers. This vehicle probably never left England, as it was held by the School of Tank Technology, before transfer to the Tank Museum in 1949. This vehicle is painted to represent a tank serving in Tunisia.

Now if someone should know what gun the Mk III should have it would be the Tank Museum.
