Thanks for pointing me in the right direction Dick
They are indeed for Rob Roy, I have a copy of Martins Evens excelent book on building Rob Roy, and ran my rule over the castings and they match up with the drawing in the book.
Dont know what I’m going to do with them if anything, they were a real bargan having checked out their cost at Reeves, I had it in mind to use them for a twin cylinder vertical marine engine, but I think that would be a bit of a beast.
Thanks again
Stew
