local shop ?
about 12 years ago I rebuilt my pump. I ask a few local garages and found a shop that did aircompressors. I took the pump in and they identified it and sold me the parts. It gets pretty cold around here, 6 months of good snow ski weather , then 6 months of poor snow ski weather. so I wrapped some heat tape that is normally used to keep water pipes from freezing around the pump and I plug it in in the winter for 3 or 4 hours whenI want to use the shop compressor. I also made some dippers for the rods, drilled the caps and X ed the cap bearing surface, Like I did to My old Flathead 4 T motor.
