Hi Andrew Just following up on what you said about the Spitfire engines in an earlier thread. Is the 1296 engine marked "FD" the 1969 MKIII with HS 4's? Are these engines hard to find? From what I've read the 1500 engines seem to be problematic and the one in the 75 Spit I have is finished anyway so I'd be looking for an earlier one. CK
