Yes, it's another M551 question, but here goes:
Some Sheridans, particularly those used in Vietnam, had a M60 30-cal MG added
to the turret beside the loaders hatch, in addition to the commander's 50-cal MG.
Do any photos (of either 1:1 or model examples) of this MG and its mount exist? I have been unable to find any.
I'll post some pics of my Sheridan project tomorrow (or if I don't have
the time, the day after). Since it is so big, I thought I'd put as much detail as possible on it inside
and out!
