The B3 Bomber Jacket is of W.W.II vintage styling. It is made of USA tanned double faced sheepskin leather that is of one thickness. Finished Dark Brown on the outside and the sheep fur left on it on the inside. Although there were slightly different versions of this jacket produced during the war time rush, this is our version. On waistband and cuffs the seams are turned fur out to reveal about an inch of sheepskin. There is an inside wind flap that tucks under the zipper, a wide pocket that opens diagonally and adjustable leather straps and the collar sides of this Jacket. Seams are reinforced by stitching strips of goat hide on them. The Zipper is number 10 brass. Please allow time for us to make this jacket up as there are limited quantities on hand.
