Good news since last posting was a message saying for the cost of postage, a new hardback copy of the 1912 catalogue by Cavendish would be on its way to me, so gratefully accepted that kind offer.
Sourcing the missing parts ie smokestack, safety valve and a non working pressure gauge would cost me approx £200 from a seller in Germany so this bit is on hold at present.
I did get a fairly complete second poppet valve engine, 110mm flywheel which I do not need, so hopefully it will find a good home with a member one day.
