Slocomb Mic Adjustment

I have an old 1" Slocomb analog mic that I'm trying to refurbish. I have lapped the faces and I need to re-zero the thimble as it is now about .0005" below zero. I have searched the web and there are some scans of the instructions, but they are too small to read. Anyone have the info that can be emailed as a PDF so as to be readable? Another problem is that what I think is the zero adjustment nut is frozen in the barrel( threaded connection) and will not move with a reasonable torque applied. It's not rust but could be congealed oil. I don't know what else it could be. It is supposed to be hard to turn so as to be self locking, but it is really frozen. I'm considering applying a bit of heat with a hot air gun. Any ideas out there? Many thanks.

RWO - I'm not sure if you saw this thread, or not. Others here (in this forum) have found these Slocumb mics interesting, and they have their own little quirks. Maybe this will help... : http://www.practicalmachinist.com/v...slocomb-micrometer-repair-185226/#post1160011
