eBay
I bought a large lot of clock parts from an elderly clock repairmans estate. I will be listing them for a while to come.  This is a very old regulator wall clock Movement. Its complete and in very good shape as far as I can see, I dont see anything damaged or missing. It has stamped into it------------GUSTAV BECKER-------MEDAILLE  D'OR---------P 24---------------575426 ( on both plates) and some fancy emblems stamped in like crown and anchor etc. Also comes with the original rear mounting plate which is complete and VGC also. This is a very high quality made part. The arm hanging down does have the adjustable pin that drives the pendulum back and forth.     It is sold as is for parts or repair. Please look at both pictures as I am not an expert on these. All the gears and parts look very good.
