Can't quite see how they could do that unless it's on a CofA on the N-register perhaps?
If you are into that sort of flying (and who can blame you) there's a chap at Sandown with an N3N-3 (imagine a Steerman but bigger!) on a public CofA that he does training on. Having been in both (my hours on a Harvard were in a military one) I can best describe the N3N as an open cockpit Harvard and superb fun. I think that there may be a write-up on it in the next month or so in Flyer, but failing that drop me an Email and I'll give you his number.
