Title: LBSC Duplex Feed pump
Post by: Jo on December 06, 2012, 06:01:51 PM: Last night I acquired another set of castings ;), They claim to be for the LBSC Duplex Feed Pump, I don't know what one looks like :-\ does anyone else?

This is what I got for my pennies:

A stick of castings. And a set of drawings from a company that went out of business long before I was born:

I have no idea what I am going to do with it. It is potentially another demonstration piece that I could use when I give my turning demonstrations on the Cowells. I don't really want to use it as spare gunmetal if it is of use.
