All the box hinges had a lot of surface corrosion. 5 of them were from the mount and OTA boxes and the other four were from older Unitron OTA boxes. The newer ones are clear zinc plated where the older ones are nickel.

And replated. There are three different manufacturers here. The top one, which is early and originally nickel plated, has an oval logo on the back with “Ant” in the oval. The middle one, which was also nickel plated originally, is stamped N.S.B. and Japan. The third one was originally clear zinc and is stamped Arch Japan.

Every little original screw and latch was polished with Mothers. Here are the latches for the EQ mount box, left ones unpolished, right ones polished.

Unitron emblems from boxes cleaned up. The bottom one is a foil sticker and was on the OTA case.

Inside. You can see the refinished bolt that holds the counterweight in place.

Next it was time to clean. I like using Formula 409 to clean up dirt and grime. Here is one of the mount adjusting knobs before and after a scrubbing with a toothbrush to get all of the grime out of the nooks and crannies.

All the black surfaces were cleaned. Everything had a few nicks here and there but not enough to justify repainting. I took some of the Rustoleum satin black, sprayed in into a cup and used it for touch up paint on the satin black surfaces. The green felt was all in great shape but coming loose in a few spots. I reattached these using 3M spray trim adhesive.

The optical tubes had a few nicks so these were touched up with gloss white.

Here is the 10x40 finder and mounts.

The clock drive has a hex shaped part that fits into a special version of an RA adjusting knob.
