Turner in Birmingham [1834-1890] and Turner in Reading both made shotguns.
T.Turner,Birmingham held several patents related to rifle and non foul rifling of barrels.T.Turner 2 was proof master at Birmingham in 1899.
T.Turner of Reading was I believe one company that developed light weight 12G shotguns.We also see illustrations of Turner guns built on the semi hammerless patent of D.Bentley #17037 of 1884, these guns often have a London address.
