It appears that Aero just added an "Indiana" (Indy/Indiana Jones ) jacket to their current line up. In their description, Aero states "new offering from Aero is the vintage jacket that could well have provided the inspiration for the film jacket, this is what such a jacket really would have looked like in the 1930s, in that fictional world of course. In reality we’ve taken the spirit of the film jacket, toughened it up considerably and given it a 1930s makeover by building our version in heavy Front Quarter Horsehide, the first choice of hide for an Adventurer’s jacket back then and a leather that really would stand up to being dragged behind a truck."
Much has been said from the "purists" regarding this jacket, whose position seems to rival the A-2 purists on this and other forums. However, I think that a lambskin jacket would have been in tatters within a week of one of Indy's adventures. A goatskin would have endured much better than lamb. A FQHH might have fared better than the goat. Although I did not recall the lining, I would imagine that the "tough as nails" cotton drill would have lined Indy's FQHH jacket.
I have a Gibson and Barnes Indy jacket that G&B calls their Expedition jacket in brown goatskin that seems to be an accurate iteration of the Indy jacket, although I am by no means a purist on any jacket that I own. I am not fond of the Indy zipper zipper that to me as a right handed guy is on the wrong side and somewhat awkward for me to use. My Indy jacket is a 44 long, which is what I require for my long arms. I found this jacket on the rack at B&B when I was in San Diego a couple of years ago, and it is one of my favorite cool weather jackets. It is a fantastic "knockaround" jacket.
