If I haven't sufficiently demonstrated my mechanical ignorance about repeaters in a thread I just posted, I may make that demonstration complete in this thread. Apart from trip repeaters, I believe that all other fairly modern repeaters are activated either by pushing a slide bar on the rim of the case (which winds the spring that powers the repeater) or by pushing a large, usually ovoid button on the rim. I believe all of the latter type have a "centrifugal force governor" invented by Le Phare or the company that owned that brand name. Is this correct? I hope I won't offend anyone who treasures centrifugal force-governed repeaters by saying that I am prejudiced against them, believing them to have been a lower cost alternative to the slide repeater. Am I correct in thinking that the top firms never used the centrifugal force-governed mechanism? Is it inferior to the slide alternative?
