Sheridan loader hatch MG mounts

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!

I haven’t seen any photos of these mounts, but just guessing I’d bet they took the M60 mount out of a jeep and cut it down to a usable size and welded it to the turret roof. A Sheridan’s turret roof is steel, we used to hang magnets from them all the time.

Don’t have pictures but what Steve said I did see on M48 and M60 over there when I was there in 68-69. Then held with a bungy cord to keep them from swinging in the way. Hope this helps===== Stephen
