I've noticed this before, but browsing the skilift.org install sheets reminded me. Mount Snow's old Summit Local had a replaced drive terminal. skilifts.org says the gearbox was replaced in 1984. The entire top terminal must have been replaced as well. I know this because Yan terminals didn't have the rounded front tip, as shown, till the 1980s. The Local is from 1978. Anybody know what happened to that old terminal? And why was it replaced?
