The business with the drop dog retracting when it senses reverse movement would be hilarious if it weren't terrifying. Good on them for fixing that immediately on all lifts with the problem. Sawduster and Bucksaw are Stadelis, the rest are Borvigs. I conjecture that the requirements for the drop dog switch is one of those things that's highly variable by jurisdiction, so it's something that gets put in by the installers, meaning it's likely that lifts by different manufacturers will have the same part.
I'm surprised Timberline isn't on the list; it's identical to King Pine. Both were originally installed the same year, but Timberline was moved to its present location on the summit ridgeline a few years later.
Same here on Timberline so I checked NewEnglandSkiHistory.com and they have Timberline listed as a 1997 install and as a Borvig/Partek. Not sure that is correct but if it is, I suppose it is possible that when moved and reinstalled, it got upgraded components and the switch in question could have been one of them.
