My late brother was a clock and watch repair professional. My wind up 40 clocks were easily made to work well by removing the face, immersing the movement in his ultrasound clock and watch cleaning and lubricating solution. He said he suspected the movements were Big Ben alarm clocks.
I did sell my electric clock to Mike Kubarth. Pictures of it are in either my Misc photo album or 40 woodie album. It had a different retainer as you can see from the wind up clocks.
