Differences between the Buco D-Pocket models?

[bretron]

I know the obvious differences between the J22 and J23 models (eg wool to nylon liner), but what are the differences between the J21 and J22 models and the J23 and J24 models?

Cheers

Have you seen the Rin Tanaka motorcycle jacket books? There are a couple out that I am sure will have the info in, well worth seeking out.
I do have one of the first editions but I cant get to it at the moment.

I know the books you speak. Thx for the recommendation; but I must admit, I find it more fun to spend money on the items and not on books about the items It's odd to me that I havent been able to find a source anywhere online on this subject... Talk about A2s or Irvins (or the zippers and thread that was used to make them) and watch out!!!!!

Anyone with the Tanaka books in hand that can help enlighten me and the rest of the Internet?

What I meant was if you can access these books then you could get the info from them and go from there, s I think you worked it out
Try a public library? They are rather expensive on the outlay so I dont know what libraries stock these days. Ours had a copy of the Flight Jacket A2 book but it went missing, 'Lost' I presume.
