Walker & Hall 6oz hip flask. It is more than 40 years old but has never been used. It has a fine cross-hatch pattern, which gives it a vintage look. It has a space on the front for engraving. It has no scratches or other damage. It has been kept in the original box. However, it does have some minor marks and/or imperfections which I believe result from the manufacturing process. I believe it is pewter, although I have no documentation stating this. It is stamped "Walker & Hall" and "Sheffield". Walker & Hall still sells hip flasks in silver and pewter. No other materials. It has no silver hallmark, and Sheffield is a famous centre for pewter production. So, I think it is pewter.
