I am selling because I have two...both 42, both a tad too large for me. But this one fits a bit bigger than the other one. I think this one is horse - has the stiffer hand that often comes with horsehide. But of course I cannot be sure. Sick creasing on left sleeve - looks really badass. All zippers original and working - Conmar as main and Scovill on sleeves. Diamond pulls - Scovill. Lining good, one small lining repair - see picture. Earlier, more desirable white label. More pics or measurement details on request. Measurements with jacket zipped up and lying flat. P2P - 21.5 S2S - 18.25 Sleeve straight down - 25 Back - 25 Hem - 21 (this cut flares out at the hem - nature of the beast) Asking $329 shipped in the US, contact me for shipping elsewhere. For information I am 5.9 and 145# - see what I mean??? Too large! I need a 40!
