I come across Kirk guns from time to time. He also retailed cartridges with the names of The Champion, The High Velocity, The Marksman and The Land of Burns making reference to poet Robert Burns who was an Ayrshire lad. All the ones I have seen seem to have originated in the Birmingham Trade.
I have him at Union Buildings, 36, Smith Street, Ayr from 1900 to 1905 then at 46, Smith Street until around 1940 later moving to 25, Kyle Street then last known trading as James Kirk Tackle & Guns from 1984 to 1988. Lagopus.....
