I know that this is coming years after the original post so my apologies up front for that. I am currently trying to get a Barton-American pump up and running again (UA-50) that is mounted on a 1958 Chevrolet Viking 60. I am looking for an original manual, details on the hose functions that are connected to the pump (not the fire hose) and also a possible source for the correct Marsh gauges for the truck. I have the intake pressure gauge which is non functioning however the discharge pressure gauge was replaced with a later Span gauge (oil filled) which is incorrect. I do have all of the details on the truck (build plate, etc.) if someone is still interested in that data for archival purposes
