Again I'd have to check Evan, but I think both of the PR19's the BBMF had at the time (one since sold) had originally been presurised, but the equipment was removed when put back into 'serice'. In fact, I'm virtually sure they would have been, as the intake is on he cowling. Far as I recall, it was only the first few, 12 or so(?) that weren't pressurised. Again, I can check and let you know. I'm a bit peed off with my mate, he told me he'd bring the transparency scanner to my place, so that I could scan all my slides and negatives at leisure, rather than have to keep going to his office. That was nearly three weeks ago, and he still hasn't turned up! He was bringing me a new computer keyboard too, so I hope he won't be long, my present one I think is f..er.. not working properly!
Soon as I get the scanner, I can get cracking on the pics for you.
BTW, I've seen the ad at Model Hobbies for the Airfix 1/72nd scale Spit PR19, which is incorrectly shown as PRXIX on the box art. (From the PR19, the numbering changed from Roman to Arabic.) Anyway, it's £5.29 at MH, whih I suppose is reasonable these days for a 1/72nd scale kit, although it seems like daylight robbery to me, considering the price of the average 1/48th fighter-sized kit, or some of the newer large kits by Revell Germany.
