A local pal has one. The it's spring loaded, when you pull the knob on the side back the arms retract iirc.
Interestingly enough, the tool was acquired for free. My pal was helping a widow in Sarasota clean her garage of her deceased husbands stuff. The stash included two Paramount Track tandems in rough shape and most of the inch pitch drive train parts to go with them, not to mention countless other tools.
