A potential client has contacted me regarding a Herschede 2 weight, 9 tube GF, circa 1925. This is the model with the weird chiming set up. The clock has been recently repaired, about a year ago, but it still stops after several hours. A limited inspection has shown that there is no friction tension on the shaft for the chime (it slips; and the fan assy. has been soldered for some reason). This causes the tempo of the chime to be very fast. There are other problems as well. I seem to remember an article on this movement many years ago, but can't seem to find out much info. Conover's book does not cover it. Before I get into it, I'd like some more pictures and info.
