Parker rebated breech face

[John Truitt]

they are out there. there are several pictures in parker pages.
I have one a ten gauge early lifter short frame with non radius frame/ barrel on a #3 frame.

The one I posted about is also an early short framed 10 gauge lifter on a #3 frame.

[John Truitt]

my gun dates to 1878. has the wedge forearm

my guess was for brass shells? I don't really know. But she shoots just fine with modern shells as well.

the rebate is deeper at the bottom than at the top of the circle.

Many Jones underlever guns, especially Double rifles, has rebated breech faces. When the under lever was swung, the barrels were free to move forward.

Mine also dates to 1878, ser# 113XX. 10 gauge, wedge forearm, #3 frame & also has the tapered rebate which I assume facilitated opening and closing the gun. Guess there's more in the Parker book than we know of.

I've seen rebated standing breeches on European under lever rifles and shotguns that moved the barrels forward slightly before swinging open. This is the first I've heard of Parker Bros using a rebated breech. Indeed the shorter frame facilitates the moving of the barrel away from the breech face but also requires the action to open further so the shells will clear the top of the frame for loading and extraction. Im thankful they got away from that design!

I too have a gun with the rebated breach face When I get home on tuesday I will take a photo of it, as John says mine is deeper at the bottom than at the top of the circle also Gary

I do believe I have seen English guns where the breech face was the opposite. And the barrels, when closed, would slide back and interlock with the protrusions on the breech as a final locking feature.

the higher grade Darne French shotguns have this feature.

J. D. Dougall had a patent on his "Lockfast" action. (Patented in the mid 1860's - originally for a pinfire cartridge) On the standing breech face, there were two raised bosses/roundels that fit into a recess in the breech of each barrel. The gun had a lever along the right side of the receiver that, when turned down, moved the barrels forward approx. 1/8" and then allowed them to swing down.

Many others did something similar (perhaps upon expiration of earlier patents). Collath drillings have the same basic mechanism as Dougall's, but it uses a very large lever underneath the forearm/foreend to actuate it.
