Hello, I recently obtained what was described as a pewter hip flask made by James Dixon & Sons. I am interested in finding out two things about this flask: first, about when was this flask made; and second, is the flask made of pewter or Britannia metal? The flask is 6 inches tall and 3 1/2 inches wide and about 1 inch thick. It has a knurled screw top with a natural cork seal inside the top. The only markings are on the bottom include: in the center of the bottom a trumpet and banner uderneath which is written "James Dixon & Sons" and under that "Sheffield." To the right of this is stamped the number "1413." To the left of center is a hollow inverted U shape--sort of looks like the receiver on a telephone set. There are no other markings, not the word England or Made in England--nothing else. Any information would be greatly appreciated. Cheers, John
