Hammer gun lock assembly
 

Is there a parts schematic? It would be for a top lever hammer gun.

i have not seen a Parker specific

but google any sidelock hammer diagram -my first "sidelocks" that i disassembled were flintlocks - it translated quite easily to breech loaders

if you are going to take one apart be sure you understand how to compress a spring

There are pictures of the lock assy assembled...

Enlarged for detail...

Austin Hogan posted quite a bit about the inside of Parker hammer guns. I'll try to find some or someone a lot better at it than I can look.

BTW

if you are new to taking a lock (or just about anything for that matter) apart for the first time

draw an outline of the item on a piece of paper- tape the piece to the paper as you remove it with an arrow to the location and outline of each piece on the drawing - adding an order of removal number would not hurt

it especially help make sure you do not mix up the screws

Take pictures as you go for later reference.

The screws on Parker locks are numbered.

Huh?

Brian,

That was my reaction as well. At the Fall Southern a few years back I watched Dave Fjelline working on a Parker lock and he mentioned it as well and showed me and the fellow who's gun it was. I can't recall where the numbers were, but I did see them.
