Clock
Karman Ghia clock guts. I paid $5 for this (used) clock at the BugOut Bug Show. I saw others for sale. My clock apparently had one problem that I didn't have to open it up to fix: bad ground. Make sure the little copper tab under the spanner nut on the rear of the clock is well grounded, and clean of corrosion. To get those nuts off, I ground a square notch in a screwdriver blade.
