Not enough of an expert to give you dates, but here's a start. The first one is the standard A4 style that is most common in my experience. Some time in the 30s is when this came into being, along with the adoption of the A4.
The middle one is 50s vintage and is specific to the M37 tank gun. It is rare and I am in need of one, hint hint!
The one piece on the right came late in WWII I believe. I know that Saginaw produced that style as I have seen them so marked, but never saw pics from WWII with that style mounted. I assume they must have been made during the war as Saginaw production ceased along with the other mfgs at the war's end. While RIA produced A6s and M37s in the 50s, no more A4s were made after WWII, as far as I am aware.
Of course, this is only to the best of my knowledge. I don't know everything, despite the appearance I create around here that I
THINK I do!
Any other input, backing me up or gainsaying me is welcome!
