Hi Folks, Further to my earlier posting on this subject, my friend and I have been doing some more research and have found out a bit more information. You will remember that he was looking for a source of castings for this engine. Well we have discovered that the original design was by Henry Greenley (we knew that) and that he described it in the ME in 1933. We now have a list of the issues concerned, they range from Issue 1652 to 1697. I wonder if anyone has access to these issues and might have a few minutes spare to have a look in one or two of them to see if there is any mention of who is supplying the castings, or alternatively if there is anyone advertising that they are supplying the castings. It is very slight chance, but knowing the original supplier might enable us to find out who is the current supplier, if there is such a company. Cheers, Roger Mason, in St. Agnes.
