I have an M66 MG Ring. The ring itself appears never used. Rotates well. Other parts used, but all are serviceable. Includes: all three leg supports, .50 cal MG mount (missing a pin), ammo box holder for MG mount, two mounts for additional ammo boxes, back rest pad and mount, expended brass chute and mount, barrel clamp, U-bolts for mounting legs (a little rusty) and a bag of bolts for assembling unit (new). Have some duplicates parts. Not an expert but believe the only parts missing to mount the ring are the reinforcing brace that goes on the back wall of the cab and the mount for the leg that attaches at the passenger door. Thought I had one but can't find it. May turn up. And I think installation requires two of the triangular adaptor plates, not sure.
Located in Louisville, KY. Pick up only. Make offer.
I am in the process of downsizing so I can move into a patio home in the future, so stuff needs to go. I also have some odd and end Duce-and-a-half related that I would gladly throw in along with any duplicate parts just to get them out of the garage if you are interested.
