Start anew, restart, re-invigorate, re-commit ... whatever... go get 'em, and please make sure to post lots of pics!
Thought I might try to address your second question first...
Also, regarding the Sherman (In U.S. units) it seems that M4A1s and M4A3s were by far the most common in the summer/early fall of 1944, what ratio (approximately) were these in? Would some early M4s still be around? And how many 105s vs 75s (approx, just need a rough idea) would be appropriate for the period from landing to say, November 1944? Regarding the British, how many Fireflies would they have had to standard 75mm gunned shermans during this time? The breakout period is my chief interest. Thanks!
US Army settled on the M4A1 and M4 as their standard Shermans in 1941. The M4A1 was produced more quickly and in larger numbers, and so became the dominant version in US Army service in 1942.
Then, in 1943 the switched to the M4A3 as the new standard, and reclassified the M4A1and M4 as alternate standards.
By November of 1944, in France, the M4A3 would have been about half of the total medium tank strength. The remainder was made up of the M4 and M4A1, with the M4A1 being a little more common than the M4. Maybe about a 5 to 3 to 2 split (M4A3 to M4A1 to M4).
Individual units tried to stick with one version. This was particularly true of the M4A3 vs. the other two, because the Ford GAA engine in the M4A3 was a very different beast ... the performance of the tank was higher, the care and maintenance was different, and there was no commonality in engine parts (beyond the gas). Units operating M4s and M4A1s saw the two as more interchangable, as they had the same engine and performance.
At the time of the Normandie landings there were proportionatly fewer M4A3s and more M4s and M4A1s in action. Most were the mid-war upgrades with the M34A1 (wide) gun mantlet and applique armor plates on the hull sides and (less often) turret front/sides, but with the smaller protruding hull hatches.
In the MTO (by this time mostly the Italian campaign, but then also the Anvil/Dragoon landings in Southern France) the M4A1 was the more common version. M4s were second, and M4A3s were rare, if present at all. This is because the Overlord build-up had most of the new formations, which were generally entirely equipped with the newest vehicles, and the M4A3 was the last of the US Army versions to ramp up production.
The Sherman 105s were always in high demand and short supply. They were grouped into 3-tank assault gun platoons at the battalion HQ level. Very popular, but production only really caught up with TOE levels at about the end of 1944. Whatever the TOE said, they were often attached at the company level, or even parcelled out individually, depending on the mission.
British Sherman squadrons typically tried to field Fireflies at 1 per every 3 75mm armed Sherman at the Normandie time frame, going up to about 2 per every 2 75mm armed Sherman by the end of the year.
Or so I believe. All from memory at the moment, so if anyone knows better, please do correct.
