Most of what you have there looks to be the conversion for a Ammomaster progressive to the Ammomaster single stage.
The single stage Ammomaster once had the ability for up to 50 BMG.
Find someone with a Ammomaster, and I bet they would buy it. I looked at them when I had mine, just for the sake of continued use when parts were no longer available to upkeep the progressive aspect. I bought a 1979 Corvette project, so my press was sold to buy tires.
