View Full Version : What's this screw for?

What is the purpose of the screw on the end of the dolls head extension on a Parker Repro? Is it just there to hold the dolls head in place? The dolls head extension on my 16 gauge Galazan barrel is not a perfect fit (open space is less than 1/8") and its not engraved like the barrel in the photo here (pirated from GB). The gap is somewhat unsightly and the un-engraved extension looks unfinished. I'm thinking of getting a new extension made to fit and also engraved like in the photo. It would be a simpler job if the screw just removed the dolls head without messing up anything else. I don't have a photo of my particular barrel end showing the screw so I pirated this one from GB. Gun locks up tight and have not had any firing issues.

That screw is for the retaining plate for the ejectors and does not affix the dolls head extension The dolls head extension is traditionally silver solderedand held by a small screw that once in place is finished and engraved like the top rib and is basically unnoticed.

The screw holds the ejector stop plate in place. Be VERY careful about screwing around (sorry) with this screw - a very seldom-heeded admonition with Parker ejector guns is to either use snap caps or hold your hand (thumb or finger) against the ejector as you open the gun after snapping the hammers down to give the ejectors some resistance against the very strong spring force as they are tripped. Failure to do this over time is the # 1 cause of the screw stripping out, resulting in the stop plate "blowing out", allowing the plate and one or both ejectors to sail off into the blue! Losing the stop plate, or one or both ejectors immediately results in a "deep kimchee" situation which takes forever to rectify and costs nearly as much as a new pedigreed bird dog puppy. So far as the ill fit on the Galazan set, you have 2 options: 1) learn to live with it (you'll never succeed in ignoring it), and 2) have a completely new doll's head rib extension made up, soldered and screwed in place, reblued (along with the barrels), and re-engraved. With Monty Hall having recently left the planet, I don't know of a viable "Door #3".

Im just curiuos if this could be micro welded, refitted and engraved?

At that point, you would be SOL if you ever broke an ejector.

I bet a good machinist or gunsmith with fabrication skills could make a custom stop plate that would fill the gap. You might think of giving Bryan Dudley a call.

That would also involve adding metal to the sourounding rib extension areas next to the stop plate.
Bryan must be my machinist cousin. And his parnts must not have known how to properly spell ‘Brian’.

I've seen several poorly executed attempts at this. None were satisfactory.

Tom - post a picture of your barrel rib extension / frame interface. While perusing threads surrounding Galazan barrel additions, I get the impression barrel fitting (by Galazan) was hit or miss, at best.

Their son also did not have spell check. LOL

Attached are photos of the 16 gauge Galazan barrels with the ill-fitting dolls head extension. The last photo is the factory fit of the dolls head extension on an original barrel.

Origin and meaning

The given name Brian is a variant of the given name Bryan. This name is thought to be derived from an Old Celtic language word meaning "high", or "noble".

Early examples of the name are found among both the Breton people as Bryan, and among the Irish as Brian.

Kinda dispels the notion that 'one size fits all', doesn't it?

The fact of the matter here is that each and every original Parker was hand built and varations in fit exist. Similar issues are encountered with fitting a set of original barrels to a different gun. Now, your gun is a Parker Repro, where machining was much more consistent and interchangability was a lot better, but the chance is still there for variation. I personally have fitted up a set of galazan barrels to a repro and the rib extension fit was pretty darn good.

The Galazan barrels were made complete and finished, then sold. Not made and fitted for and to the individual gun they would be going onto. So, these minor fit issues are normal to be encountered. The rib extension on those barrels may fit another gun very well, but just not yours.
You could go through the work of reinventing the wheel to make the fit better, but even then... the rib matting would still not be correct.

At the end of the day the barrels do fit and lock up tight. Have not had any issues with firing or accidental opening after a fired shell. I say leave it be. Thanks everyone for their responses and comments.

Thanks for the pictures, Tom. I could fix that dolls head with some machining. It'd be tedious and not nearly worth the cost though. I think it's cool CSMC put forth the effort and made barrels available but, I'm also a bit surprised they cut corners (no pun intended) the way they did. Welcome to the new world of manufacturing, I suppose :(
