Thanks Marco!

While we're at it, here are some more:

M3 Medium, 1942, Ordnance acceptance marking "RZC":


Ram II, 1943, Ordnance acceptance marking "BOH":


M4A3(105)W, 1945, Ordnance acceptance marking "ABQ":


So who were the counterparts of Col. D.N. Hauseman? I guess it is a study on its own....

Thanks,
Hanno
