This vintage pewter tankard style mug was made in Sheffield England by Harrison Brothers and Howson. I'm not sure of the age, but I found another HB&H mug online in the same style with an engraved date of 1947. The maker's marks were more modern/recent than the one I'm selling, so I'm confident it's at least older than 1947. The company was in business from 1962 to 1950. The mug measures 3-1/2 inches high by 2-3/7" diameter at the rim, nearly 3-1/2 inches across the base. The underside is numbered 535 and marked "Beacon Pewter, HB&H, Sheffield England". There is some age but no dents or dings.
