remarkable David,
: )
Broken mainspring and stem, the balance swings freely and it runs under pressure.
Should be fine once I can figure out which mainspring it needs, 3 different varieties so far all listed for the 8AN and it's possible, from what I am seeing, the 8AN was constructed from 2 different ebauches. An FF Robert and an ETA 980? All 3 mains I've found have different lengths and widths.
Reverend?
The Case has a minor issue with the Crystal shelf, directly above the stem hole. I'm not sure what the ick is, (windshield sealant?) but it's proving to be very stubborn.
Fresh pics when it's finished.
