This trigger design is commonly found on 1840 and earlier trade guns. The trigger can also be pinned directly to the wood, the correct early technique, which generally produces the best geometry for easy trigger release.
This trigger is about .105" thick, as cast. We like the shape of this trigger for North West Trade Guns, early fusils, and similar big flint muskets.
To assemble this trigger with the pivot pin fitted directly to the wood, which is a correct early method of attaching the pivot pin, use our #PIN-3/32" steel dowel pin, and #DRILL-3/32" drill bit. Best leverage is often achieved by pinning directly to the wood. The pin can often be concealed, behind the sideplate and lock plate. The trigger plate may be omitted, or a simple slotted trigger wear plate added.
