Gentlemen, I have recently acquired a pump in a job lot of stuff which I don't recognise. It looks vaguely like an old hand operated well pump but smaller. There is a handle out of the side near the bottom which works up and down. The whole thing is about 14" tall and mounts onto a square(ish) 4 hole base with holes about 3" apart. There is a pressure gauge up to 400 atmospheres (not bar) and the equivalent psi with CAV on it. There is a makers nameplate with CAV on it and a serial number. There is also a small reservoir painted grey, the pump is black. I suspect it is something to do with testing diesel systems. Sorry about the vague description. Please don't ask for a photograph, I don't have a digital camera. Anyone recognise this? Does anyone want it? Located Oxfordshire. Thanks
John
