Marposs M1 Electron 38.81/38.76mm Ø Electronic Bore Gage 1625038722

Quite honestly, I don't know a lot about these bore gages. I bought several in a large lot at a local auction and was told that they all work. I will guarantee them to work and I offer a 60 day free return policy if not (full refund, no BS).

Please take a look at all the pictures, some of these seem to be missing some sheet metal guards and/or have flaking insulation on the wiring.
