This pump was too good to p*** up and I have gone through it. A couple of things that I have not seen before: Instead of a pressure valve, it has a aluminum tube and a stack of washers. Maybe an industrial application? I'm thinking this should easily take a pressure valve if needed? Secondly, the pump itself, instead of the usual rotor & rollers, it has a rotor style pump. I have heard this described a a "rotory style" 50's pump. Your "2 bits" would be appreciated, if I can pick these up cheap, they usually pay for my day at the swap.
It was used on ‘53-‘56 Fords/Mercs (and Packards!). That valve body and stack-up of washers (shims?) makes it look like someone’s unfinished science project. If you can find the correct valve body, springs and orfice plate and the bore hasn’t been increased, you should be good to go.
