I worked on some of the Pratt & Whitney Canada built examples many years ago. They were -MR5s, I think. One day I was given the task of calling around to find a source for top overhaul kits. Everyone I spoke to got hung up on the dash number I told them I had. I explained to one gentleman that these engines were Pratt & Whitney licence built engines, which might explain the unfamiliar dash number. There was a pause at the other end, and finally he said, "Son, that's like telling me you have a Ford engine built by Chevy. That just can't be right".
I'd like to learn more about the R-1820 (this seems like a good place). I was a (pretty overwhelmed) apprentice back then, so much of the information that was being fired at me just didn't go in.
Further to the original poster's question, would an R-1820 dash number give a clue to its manufacturer? For example, is a -MR5 automatically a P&W Canada built example?
I have a data plate from a Canadian P&W Wright 1820 It is 983C9HE1 1820's were built by Wright,Studebaker, Lycoming Canadian Pratt & Whitney and some Eastern bloc countries. The Aircraft Engine Historical Society web site Enginehistory.org has a wealth of info on aircraft engines
