I know that 20x102’s rarely have a headstamp, but i have 3 ‘bunted’ Ones ( from Denmark [M55A2 - AMA] , France [OEI - MR] and USA [Experimental T61E1 with M99 projectile - FA)]) and a few ‘stencilled’ ones (all French M55A2 TP - TE) in my collection.
Are there 20x102mm headstamps known from other manufacturers/countries ?
Thanks.
