Tang locking screw on high grade guns
 

I have seen it on the Prototype A-1 and some custom guns, but has anyone seen a small lock screw used for the tang screw on “regular” production high grade Parkers? The one under the top lever.

I went through TPS and there are not many views of the top of guns with lever open.

Here is one example, although it’s not exactly a regular production high grade Parker!

Yup, that is what I am talking about. Wondering if maybe it was more common that I think and just not seen due to top lever being in the way.

I saw one on a AAHE competition gun that Steve Barnett had at Addieville three years ago.

Well, i would not call any high grade Parker “regular production”, even though I did refer to it as that. I more meant Factory production as in not a prototype or after-the-fact custom. Each and every one of these guns is unique. I just wanted to make sure that this feature was in fact used on some guns.

Brian, the example that Channing provided is referred to as a French lock by toolmakers and machinist. After looking at the picture closely I believe the lock screw was added later to correct a customer complaint of a loose tang screw. The lock screw head does not match the engraving on the Tang screw head and the lock screw head does not appear to be flush with the tang. The serial number is not in a range that an engineering change would be expected to take place.

The engraving on the screw may not match, but the ring in the engraving around the locking screw hole looks legitimate.

I figured that's what you were after Brian. I thought I had saved pictures of another example. If I can find the pics I will post them.

This link shows the picture a little better and confirms what Chris wrote regarding the engraving.

That looks original to me. Generally the minor screws on the action will not be engraved the same as the major ones. And the surrounding engraving does look right.

In addition to the ring engraved around the locking screw, the tang screw engraving around the concave 'pocket', for the lock screw, has no signs of a clipped edge.
