Vintage Denim?

I think 42 and 44 have the side strips and from 46 on it's the t-back.

From Mirror Ball: 
" * Sizes 42 and 44 feature side panels.
  * Due to fabric constraints, sizes 46 and 48 feature a seam along the center back."

I've not seen that with vintage examples. The side seam inserts could just be made larger with each size, so no need for a split back. I've also read somewhere where that is the case  - not sure where - The 501XX denim jackets book maybe?

I think the two panels used were too small for a complete (adult size) piece, so the odd jacket was made with a split back, as a sort of efficiency measure, using up good usable pieces which would have normally been binned(?) There's not enough consistency in examples to give weight to Mirrorball's theory, but you never know.

Forgot to say, that Mirror Ball is describing/quoting FWs 1951 Type 2 jacket here.

@cool_hand here's a type 2 T back, courtesy of @LazyS. As they state, the T back was for garment sizes E (stands for Extra), EE, EEE and EEEE (sizes 48, 50, 52 and 54). I think Csf repro'd a limited run.

Just found this on the lvc thread 😂 There was a video to accompany it but it didn’t move over.

Well I can contribute to this thread to the least. From what I've learned a late '66 pair, late because of the chainstitch on the back of the back pockets?
