Thank you for the quick responses.
You are correct, the first item says GW not GM and is clearly a winch part. Item 2 does not seem to mount in such a way as to traverse a turret therefor starter application seems correct.
How about trying one more challenge? Many years ago I bought two very heavy differentials from a large military surplus yard. I thought at the time they were controlled diffs for a tracked vehicle. They were apparently built by Oshkosh and were military products exclusively but one is marked experimental serial #1, second is serial #4. One has inboard disk brakes the other not. Does anybody recognize these or can speculate on their application.
Again, all comments appreciated. BP
