A Fine Victorian G & J W Hawksley Powder Flask

A very good copper and brass powder flask for a gun with the oak leaf design incorporating a fox and stag head, the nozzle stamped Drams and graduation values of 2?, 2?, 2? , the nozzle signed G & J. W. Hawksley, slight dent one side at the top of the body, and in working order. Overall 8 by 3? inches. See THE POWDER FLASK BOOK, Ray Riling page 315 fig 580. Riling says in the book that the flask illustrated as fig 580 was made by Hawksley for Barton of New York and implies that this was an exclusive design to them and does not mention having seen one marked Hawksley which might suggest that this is rare.
