These vintage mittens were made during WWII and are named to a Captain Bill Grall.  They are fully sheepskin, with a tanned finish on the hand and a raw finish on the gauntlet.  They have what looks to be a horsehide reinforcement pull panel on the gauntlet, as well as a horsehide gusset. The leather is still supple and the sheepskin is in great shape.  Though they appear to be a handmade, non issue item, they would match a wartime sheepskin B-3 or Irvin, or are perfect to go with a vintage motorcycle jacket.
