Flintlock Diagram

[Iron Patch]

Wanted to stick this somewhere for future reference and guess here is as good as anywhere.


The Flintlock

The following photographs show both sides of the flintlock mechanism, along with descriptions of the annotated parts.

Thanks for the diagram Iron Patch. Good reference. Over the years I've found several flintlock mechanisms, just curious...will the vise screw always have a slit on top? Seems I've found some without the slit but definitely found in an area where early gun parts were recovered.

I am definitely not the one to answer questions about gun parts, but since early furniture brass hardware has very similar screws I think that would have to be considered too. That said, a screw with no slit sounds better suited for the gun than being useful to hold together furniture.

Some jaw screws have a slot, some have a hole, some have both.

Many early locks did not have flys, bridles, or bridled frizzens (frizzen bridle not listed... the extension from the pan that the frizzen screw goes through).

This lock is not tapped for mounting screws. It is also atypical in that the frizzen screw mounts from the inside.

Frizzen, BTW, is a later word. Early terms are battery or hammer. But when percussion cocks started to be called hammers... yeah! confusion!
