Hi I have a book on the M-10 that I am using walk around from Squardon but don.t have a clear view of all the counter weight bolts like how many per side, so does anybody know I have replaced them as to their being oblong and not in the right place
This is the earlier one not the Duckbill one but the two earlier ones

Thanks

Tough question -- I have yet to see a clear shot of that part of the earlier M10 turret.

An educated guess, based on the later counterweights, which probably weighed the same as the early counterweights, is four bolts per weight. Those early counterweights stood off a bit from the turret armor and probably only went in through the two points on each weight that touch the turret.
