Very Early Museum Piece Antique Hand Held Fly Tying Vice

Rare 1800s Hand Held fly tying vice, in original condition, I’ve researched this back to 1800s, see pics of an Illustration plate in The Fly Tyers Handbook printed 1886, solid Ebony handle with age related crack original patina unrestored condition, I’ve only ever seen one other of this vice, certainly a museum piece as also shown in The Fly Fishing Museum Fly Tying Vice section as shown in pics. One for the fly tying collector enthusiast. Probably the earliest ever bank side Travel vice!
