Those pieces are in much better condition than I usually see them. The lower ridge reamer, which I have a twin to, is supported at the top of the cylinder by those spider like legs, they ride on top the block, the lower one is missing. The upper one looks like a Lisle, have a twin to it also. The crank handle barely looks used, I believe it turns the valve that is placed in the valve refacer on the left. Sure would like another photo of the screwdriver device, but a stone refacer seems likely. Nice find.
