I just got traded what looks like a mount for a M-60 on a tripod, but its not the ones I am used to seeing. It appears to be a 1919A4 pintle with a M-60 adapter that has a spring clip on the front and a groove that the reciever would clip into in teh rear. I will try to get pics posted soon.

Anyone know what this may be? I never was a machine gunner, so past a few classes I don't know much about the stuff, and we never had any mounts like these for ours.
