I don't know I have the Indiana Jones jackets made by wested and the lamb skin which was used in the movies for the way it stretches and hangs looks exactly like the Sideshow jacket. Cow or goat has more of a grain to the leather, while in reality the lamb skin coat would've been torn to shreads anytime Indy pulled one of his stunts. I have both a goat skin and a lamb skin Indy jacket and the lamb skin is the exact replica, so Sideshow actually has it right.
Exactly.
