Would like to put these up for trade, before I do that I would like to know if anything is wrong with them. Any thing to look for or check?

If you have a ball bearing or gage traceable to NIS standards, that will tell you if they are in calibration. If not, it is quite easy to calibrate them if you are aware of the procedures.

Check the measuring edges with a light, they should be sharp and flat against each other.. If not it could have been bent during a fall and won’t measure correctly.

For the calipers just check a 123 block. If they read within a half thou on all 3 dimensions they are likely just fine.

The mic is fussier. You should check it on a micrometer standard if you can. If you have access to some gage blocks, I would check it at .01000, .5000 and 1.0000. That will show that it is reading correct at various points on the range.

What are you looking to trade for? I'd be interested in the mic, particularly, but both for the right deal.

If you have access to size blocks also check the micrometer at .100, .105, .110, .115, .120
This will show out of parallel faces as the the error will show at some of the positions and not others.
