Hi Everyone,
I found this vernier in the bottom of one of my 'work' toolboxes, which I dont visit much these days.
It was covered in a sticky substance---I have no idea what.
It wouldnt move at all.
I sprayed in in metho and then inox and let it sit overnight.
I found a jewelers screwdriver and managed to ease the tiny screws on the top of the sliding jaw. I assumed they held pressure on tiny internal gibs or similar.
I need to stress, I took gentle care not to strain or stress anything.

After several floods of metho and then inox , the sliding jaw moved about an inch and then froze again.
Ive sprayed it with shellite to sit overnight.

So my question is before I go any further, whats the best approach to renovating this vernier?
Since it is a 'work' instrument, I know it was a good quality one, and I know it would have gone out of service when metric was introduced.

Usually I use a digital vernier that changes metric/imperial at the touch of a button, but the one I have is not very accurate.
So I'd like to get this one going if I can.
Please help!

regards
Brian
