For those who owns the Aero Leather's unknown 1756, most likely a Perry jacket, please kindly comment on the body pattern vs. their 15142 or 18775? Historically, it seems highly plausible that the same manufacturer tended to keep the pattern throughout their contracts and just make local changes (minus the collar stand, pocket flap shape etc). The result is all the Aero's fit about the same etc. (John, Andrew, anyone, feel free to correct me). Now, Aero says they copied an original Perry, therefore it should be a Perry pattern and not an Aero pattern with Perry's local details. Based on the website photo, the body looks quite like a 15142. On the other hand though, the Hudson Valley makers starting from Werber, may have all "copied" each other? My experience with the Aero patterns is they tend to have wider's, slanted shoulder, and the torso flares out toward the hem (like a trapezius body shape), and with pretty slim arms. Opposite to a bodybuilder's shape with roomy shoulder and upper back, tapered in at the waist. My size 44 Aero 15142 has plenty of chest room but not so much upper back (forward reaching limited), plus slim arms, and a roomy waist, opposite to my build. I also have an Aero goat (soft) 18775, size 44, longer in the body, roomier arms, but again, it's softer leather so it's hard to compare with the jerky HH. I want to buy an Aero A2 (made by Aero) that has a different body pattern, therefore I wonder if this is at all realistic?
