Is anyone (other than >Canadian techs) familiar with them? I have seen the "Lost Motion Compensator " in several different high quality verticals, built around the teens and twenties in the US. I believe these were all "Wessel, Nickels and Gross actions." They were a pain to work on but it was a beautifully crafted action that seemed to work very well. I also seem to remeber some unuasual jack spring designs simular to John's description of the Bell upright in some 20's vintage Chickering verticals. (Also a pain to work on). Scott Scott E.
