A 1911 Bentley and Playfair [recently amalgamated with Hollis] Catalog is for wholesale only. All items in the 46 pages are made for the Trade, from barreled actions to finished guns. One could order extras like we order automobiles nowadays. They offered boxlocks, sidelocks, rook rifles, double rifles, cape guns, falling block rifles and much more. Attached is a picture from the catalog of offerings to gunsmiths who want to finish up the guns on their own. Note the single trigger is offered at a substantial price , relative to the barreled action. Does anyone have an idea of what kind of single trigger is offered ? The cut shows the trigger details.
