I ran the arm in and out several times. The dial indicated seems to be working correctly. That said, the crystal is missing so something bad happened to this at some time in the past. Certainly needs the crystal replaced. There are a series of pictures of the dial as I compress the arm.
If this had the crystal, I would be asking a lot more for it. The dial seems to be working correctly.
