I am seeking history of the shotgun maker George Armstrong & Co of Newcastle which ceased production in about 1915. My great grandfather George John Taylor Armstrong of Cradock South Africa passed down a double barreled George Armstrong & Co shotgun engraved 'George Armstrong & Co Cradock No. 715' , see attached photos. We believe my great grandfather, who died in 1914, had a branch in Port Elizabeth and Cradock and was involved with the Newcastle operations. Any further information would be appreciated.
