. . . does anyone have a solid terminus ante quem for this Birmingham partnership? I see from an interesting post by geojoe that a likely Mr Beilby's involvement likely falls between 1818-1827 (bankruptcy notice & Will). . . . it came to me in near-implausibly good condition: undisturbed nuts, handle intact & tight, straight, and with very little wear to the plate. A credit to Messrs T,G,B & Co. and all intervening parties.
