I'm afraid not...... The manufacturers issued a serail code but I've never found it anywhere other than the plate, though to be fair, there are a lot of places to look! The Army were only concerned with the T number.
Repro legs are usually made from 2" nom. bore or 60.3 CHS which are both 2 3/8" o.d, so it is likely your second set are that. I made some once and I remember that the original size was a little unusual but I can't remember for the life of me just what they were!
The grenade box is a standard US part and was fitted in various afv's, the bottom box has a British catch on it. What is the writing, I can't quite make it out?
There is desert and there is desert..... some parts have so little loose sand that stuff lays uncovered for decades, other parts get covered overnight!
The E9 was a program to space out the suspension on normal VVSS tanks to allow the use of extended end connectors on both sides of the track. The E8 program was the later HVSS suspension and wider track. The improvement in flotation and hence mobility of the E8 led to attempts to retrofit earlier tanks, hence E9.
E9 was just coming in to service at the end of the war and many tanks were rebuilt post war with it. It was a modification and could be fitted to any VVSS tank. 1000 kits were built to allow in theatre fitting.
That is actually a gross simplification as there were various other systems trialled but it gives the general idea!
Welcome Luis,
it is a pity my M75 APC is not amphibious as it has all the other features you need and is for sale!
