Carb pump & spring needed; '33 Rockne

[rockne10]

I just heard from Dave T-bow that the accelerator pump and spring (P-16038) (Pump, piston & sleeve assembly) in my Stromberg UR-2 No. A-17252, are corroded beyond function. Throwing out a request to anyone who may be able to help find a replacement pump, or carb core that might lend a functional accelerator pump. These were used in models 30-31 and 41 Rocknes and model 55 Studebakers, I suspect quite a number of other vehicles and farm tractors as well. All leads are appreciated.
