Nice find....you could have bought a surplus 75mm gun cradle and all the mounts would have been there Did you get a good deal on them? Unusual to have the gunner's head rest with it..

I had a 75mm scope on my little TD but had to make an ad hoc mount as it was on the left instead of right. My subcaliber 12 ga shotgun took out a pistol target at nearly 200 yards with 00 and I had guys bugging me to take it out deer hunting. .

Now, [>:] mount it close to the driver on the dash between the driver and passenger seats with a tube almost to the windshield...police and security would go nuts...
