I have a size 38 model 141 (naked cowhide) if you're interested. I wear a size 38 suit and can tell you that this jacket fits two sizes smaller in my opinion. I can't even zip it up. Definitely a vintage size 38 and not a modern cut. I know because I also own the 641 in steerhide size 38 and it's a much more modern cut (feels two sizes larger than the 141). Here are the measurements on the 141:
Shoulder to shoulder: 19 inches Armpit to pit: 21 inches Waist: 18 inches Sleeves: 23.5 inches Length: 25 inches
The jacket is in excellent shape (9) on a scale of 1-10, with only very minor wear. Leather is really thick and buttery soft. Wasn't planning on selling it but since it's too small on me, why not? Due to the excellent shape it's in, I'm willing to sell it for $400. Let me know if you're interested.
