I have a lovely Aviation Leathercraft B3 which I bought when I first started flying powered aeroplanes (DH82's so appropriate) in 1989. I've probably worn it three times as I feel like Michelin man in it and can hardly move. However, I also have a well worn A2 of unknown make that I bought years ago and now wouldn't be without! Apart from the obvious it's been used as a chock, windscreen protection when refuelling, as a cushion and probably a lot of other things I can't remember right now. It doesn't look showy ... more shabby than chic, but whether I look a knob in it or not, I wear it with pride!
If you want a leather jacket ... go for it! A2's are pretty middle of the road so that's what I'd recommend.
