Recessed hinge pin
 

Was the recessed hinge pin patented by PB, and if so, does anyone know the date the patent was issued. I am trying to pin down, as close as I can, the serial number range in which the changeover occurred. I posted a similar question last year and Brian Dudley responded that the changeover occurred during the 5000 serial number range. Does anyone have a non-recessed hinge pin gun in the low to mid 5000's, or a recessed gun in the mid to upper 5000's?

The hinge pin recess was patented by Charles King.

That serial number range I mentioned comes right out of TPS.

Thank you again Brian. I'd just like to hear from any current, or former, owners of guns in that serial number range who might want to share their serial numbers and styles with us.
Anybody????

SN 5711: has rhp

Just a tidbit to add to this discussion, I was watching and old western on TV the other night "Wanted Dead or Alive" They had a close up of the stage coach driver, and his shotgun rider. The shot gun was a Parker looked to be an O grade but differently saw Parker Bros on the gun barrels were cut to just beyond the for end, Hammer gun of course, Gary

Austin, I have s/n 5056 which has the old flush (non-recessed) hinge pin. Fig 3.20 of TPS says Parker guns after about serial 5500 have the spherical recess hinge

Thanks Dean/Terry, My gun is number 5868 and has the recessed hinge pin. Any one else care to share some numbers?

I believe that some of the Philly Sterlingworths had the recessed hinge pin also, Gary

Right Gary, the very early ones.

Incidentally, Congratulations on your recent induction to the Parker Foundation Hall of Fame. It is very well deserved.

Thanks Dean, It was honor to be chosen, a humbling experience! gary

King's Parent that included the recessed hinge-pin feature had run its course when Ansley H. Fox used it on his Fox Gun Co., Balto., MD., U.S.A. guns in 1898 and 99 --

Some of those early Lefever hammer guns with the recessed hinge-pins might have infringed a bit!! Or, maybe they are where King got the idea!!

I believe my gh 59374 made in 1890 has recessed hinge pin. It is also the single piece pin. Pics in general forum.

non recessed hinge pin
 

The latest gun in my collection that has the non recessed hinge pin is serial # 5598 only two numbers away from 6000 , it also has plain steel barrels notice the color in protected places, compared to the rest of the barrels

two more,

Gary, is that an S between the upper and lower crescents?

Whatever is stamped there, is the barrel steel designation stamp.

Gary, please show the other side of the frame.
A lot of folks don't know that the hole in the frame for the hinge pin is notched and the pin has a tab that fits in the notch to prevent the pin from rotating.

Dean, yes it is s in the crescents, I have enclosed a photo that shows it well also one of the other side of the frame, If you need more I have about 30 pictures of this gun, Gary

one more

I must have had a moment of brain freeze, 5598 is not two numbers off 6000 but two from 5600, sorry guys Gary

Thanks for those two new pictures Gary. That new picture of the barrel flats is much clearer and the 'keyed' hinge pin is evident in that picture of the frame.

Gary/Dean, Just to note some differences between 5598, and my 5868, there are crescents above and below the serial number on the water table of 5868 and 5 / 11 barrel weight stamps just forward of the barrel flats, a D for damascus on the right barrel and the number 12 on the left barrel. The "12" seems odd because the gun is a 10 gauge.

Very interesting Austin - can you post a picture of the barrel flats for us?

Dean, I ant you to try something for me, when you double click and triple click does the image get bigger by 2-3 times as mine does when I do that, It makes the barrel flats take up the whole screen, Gary

Dean, I'm still in the photographic stone age,( think 35 mm film ), but I may be able to get my wife to shoot some digital's for me. Then we have the problem of posting them. Last year Chris T. was kind enough to post photos of my 16 gauge Trojan for me and perhaps he'll help out again. I'll try to get some pictures taken so that everyone reading this thread can view them, but if this does not happen I will have the gun at Ernie's.

Got to be getting close to the demarcation line. Perhaps we can find "the first and the last".

Dean, Your gun # 5711 has got to be pretty close to the earliest known with the recessed hinge pin. I would submit it to the Parker Pages to start a new catagory.

Thanks for the suggestion Austin - I may just do that.
Best Regards, Dean
