Hi List, and a merry Christmas & Happy New Year
These pumps were made by Hattersley and Davidson, a Sheffield (UK) firm who made a variety of brass pumps for various industries. They were magic, especially when I worked as a mechanic at the Wemblet 6's, 10 or so steady strokes would have a Continental 165 up 120psi with minimal effort. Very easy to burst cheaper tubs! to I still have mine from the 70's but regtretably the replacement leather washer are no longer available.
