Author. Very Good with no dust jacket. 1991. PhotoCopy Only; Photocopy. Manila Folder or Binder. Photocopy only of rare booklet on building triggers with measurements and what appears to be exact scaled diagrams for building various triggers. These schematics appear to be for early flintlock and percussion type rifles. There is a page showing the various weapons that used set triggers including: Crossbow, Wheellock, Jaeger, Long Rifle including Kentucky, Plains Rifle, and Sporting Rifle. The specific schematics that has the measurements do not name the rifle, but measurements are given for the Single Set Trigger, the Double Set trigger, and illustrations of Double Trigger, Single set, and Compound Single Set. There is a page dedicated to the Hartford Sharps 1875 Sporting Rifle. The footnote at bottom of that page says "a later, very well made and designed set trigger, suitable for any black powder rifle with minor modifications". It is assumed that since many of the rifles made in the era of the rifles using these triggers may have been handmade thus fitting of the trigger sets were custom for many of the guns.
