Anyone recognize this stamp on .50 Cal smoothbore barrel?

Picked up a really nicely built flint smoothie pistol recently. The lock is a small Siler but do not recognize the stamp on barrel. Anybody recognize it?

Hi,
I would say Bill Kennedy. Here is another example.

Looks very much like the same stamp though this pistol is much fancier than the one I have. Even though it is plain the craftsmanship looks good, Was concerned about the barrel and how thin the breech plug is. The one in your picture looks almost identical. Guess I'm used to seeing ones 5/8" long on rifles. Thank you for the info!

I was advised once by a master machinist friend that if the threading was correctly done, three (3) threads would hold a breechplug at blackpowder pressures in modern steel. He was talking up to 25 -30 thousand psi. The wall of the barrel in the breech area will theoretically fail first, all else being equal. Besides a pistol only needs half or less of a normal rifle charge; any more is mostly wasted anyway.

I worked for a major jet engine manufacturer back in the 60s and pulled a lot of tensile tests on threaded fasteners both male and female. 3 full threads were all that were required for the tests and the fastener would fail elsewhere than the threaded portion. 4 revolutions after the threads engaged gave that and a little more.

Thank you all for the information, with that it was pretty easy to find info on Mr. Kennedy and figure the pistol I have was from one of his kits.
