Normally I like to leave my antique clamp reels alone but I couldn't resist getting the rust and grime off this recent acquisition. It is relatively large at 2 3/4" diameter. It features a working constant check (missing a gear tooth) and a brass grasp. I hope to find a replacement butterfly screw one day for the clamp. The biggest challenge getting into the check housing was the rusty handle arm bolt. WD-40 was insufficient. I finally got it to release using the ice cube trick. I was never able to get the cage apart due to 3 wire-pin locks that I didn't want to risk damaging. It turned out better than I expected.
