The Lucchini gun was proofed in 1963.

The Belgian gun was proofed in 1924 or later. Possibly 1952-1986. However the pictures are not clear (bright) enough for me to be sure.

Charles H Crawford was a partner with George Walker of 72 1/2 Weaman Street in the firm of Walker & Crawford (1889-1901). George Walker had also traded as George Walker & Co (1889-1890).

When the partnership broke-up in 1901 Charles Crawford remained at 72 1/2 Weaman Street where he traded until 1934, and George Walker moved to 95 Weaman Street.
