Original, complete pump acquired from Jim "Mr. Wadhams" back in mid 2011. Pump was disassembled and sandblasted, primed and painted with cast iron spray paint. Brass pump cylinders are 4.5" in diameter and were honed clean with a honing device similar to those used for old brake master and wheel cylinders. Outsides were polished and then clear coated. New leather cups were installed on the two pistons and everything was re-assembled.
I have lots more photos taken during the process so if other Butler pump enthusiasts are interested, just email.
