Just received a "Clock in pieces in a box". After checking all the parts for the Schatz 53 Mademoiselle are present, they are. After some cleaning and trying to assemble it I noticed the center wheel, 4th wheel is damaged. The end of the shaft is missing the "bearing surface" post. In the repair guide appendix 79, it appears to be part 46-07. This is the shaft that goes through the front plate with a small gear pressed onto it. The shaft holds the hands. It came apart well. Any ideas where one might find one?
