I see your point, Tim. They must have been largely discarded when they became application obsolete. All kinds of gate valves existed for different applications, so I suspect the visible pump valves were just tossed. I occassionally see and here of one for sale (an original). It's the same thing with spinner/jars... if you dont find one on an old pump, they to must have been discarded cuz I dont see alot of them either. BTW, if you're looking for a gate valve that's sorta vintage looking, check McMaster-Carr. I replaced the handle on one of their gate valves with a vintage looking handle I got Gas Pump Heaven, and it blends right in with the asthetic of the Fry 117 I put it on.
