This is a great working Federal 50M-1-3457 Grinding Gage. I took it apart at the lower adjustable areas, and cleaned it all up, so it all moves freely for adjusting it for different sized Crank Shaft journals. It looks like it will actually go as small as 2.800" and as big as 5.300".
But it is marked on the rule 3" to 5". There are no problems with the carbide measuring shoes. The Gauge reads in ten-thousandth increments and works perfectly. It is in the same great shape as this one.. I can even do a package deal if you want them both..
