The clutch and pinion on the right (parts 407-7407 and 410-7410) are severely
damaged because they work against the setting wheel (part 450) to set the
calendar mechanism which was jammed. It took a long time, but I found replacements
for both sets on eBay and from Tom at Dashto.com

Actually, this type of damage is fairly common on automatics that are wound quickly
by hand. The parts are tiny and manufacturers assume that they will mostly be wound
by the movement of the rotor. Be slow and gentle!!
