LBSC Duplex Feed pump

[Jo]

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.

No I could be wrong but I don't think it is either of those...

You could ask GLR, they took over the Kennion's stuff and still sell that stick of castings.

That is the one. Looks like I got it at a good price. Still no photo's of what it looks like. I found a post by Stew that mentioned it looked interesting and can be found in "shop, shed and road" - I haven't got that book...

I think this is the one you have, the build feature of this pump is in  The Live Steam Book by LBSC

[Jo]

  That's the one  

And there is 22 pages explaining how to make one.  Thanks

It is looking better and better. It would seem I have three years worth of models to make using the Cowells at my lathe demonstrations.
