Hi all. I am looking for resources for disassembly and cleaning of a 1902 parker 12g P grade. It locks up fairly well with a slight wiggle and the lever slightly left of center. It doesn't dry fire. I suspect it's not cocking as it likely hasn't been fired since the early 80s.

My plan is to clean it and restore it. I don't have much in the area for gunsmiths although there is someone 3 hours from me. I have restored a few firearms and can do most basic work that doesn't require specialized tools.

Any information would be welcome.

Rick.

The only special tools you'll need are a proper set of gunsmithing screwdrivers.

Got those. Is there an exploded parts diagram kicking around anywhere?

I don't have an exploded view of the parts but here is a cut away view that might help.
If the link doesn't work the drawing and numbered parts list is available on the PGCA Home Page under "Technical Information".

Thanks David. That helps quite a bit. Time for a screw driver and a camera.
