Just a WAG here , but the inside diameters look to be different on each so a guess would be a old set of dies perhaps ?

They look like test gauges.

Check the OD and the ID with micrometers. If they are gauge cylinders they will all be a different OD or ID or both. That's jus speculation, however -

I can't see how big they are, but with some alterations they would work great for pressing dry sleeves out of a diesel engine :cool:.
