Nigel Browns, British Gunmakers:
Arthur Howell was recorded at 28 Weaman St. Birmingham in 1909 and became Arthur Howell & Co. in 1917. He remained at Weaman Street until 1942 but may have removed to Whittall Street shortly thereafter. He is recorded as being there in Gun Trade membership at least until 1957.
