Hello - I have searched high and low looking for a source of supply for the Hermle quartz module which was used in 1986 for Hermle series 340 and 350. There does NOT seem to be a source. (And Hermle Corp. will provide no information) These were standard movements with the timing arrangement changed to accept the quartz modulator. (These are SIMILAR to the Keininger "J" series movements made in the early 1990's except Keininger parts ARE STILL available) Can anyone assist in the search?
