Help With Plains Rifle ID?

[ghostdncr]

What have I got here?

Recently acquired plains-type rifle that appears to be quite old. Rough as a cob, broken, modified, etc. I like the look of it and picked it up for what I thought was a very fair price.

Stock appears to be walnut with iron triggerguard and buttplate.

Left side of the gun showing several more old repairs.

Barrel has one key, silver (?) escutcheons, and a pewter nose cap. Original ramrod is long gone.

Barrel signed in script "S. McK" is my best guess. Full buckhorn rear sight.

Barrel is 1-1/8" AF and approximately .45 caliber with 7-groove rifling, unknown twist. Has been cut down to 24" and the rear sight moved back 8" which suggests an original barrel length of 32" to me. Just conjecture on my part, of course.

How good is the bore? I see some rust at the muzzle. The stock is really beaten. Are there any maker's marks under the barrel?

Most likely the person the gun was made for

The bore could probably be made somewhat shootable and I may consider that later. I feel like the stock has quite a story to tell but sadly, that's lost to the mists of time. I haven't seen any discernible maker's marks anywhere on the gun. After removing the barrel I did notice an unused dovetail on the bottom flat, which may suggest a re-purposed barrel? That'd be my guess. By the way, you should be able to click on these photos to open them full size.

A shot of what's under the wood. Tenon looks spot welded in the photo, but is just heavily staked.

The lock is badly worn and has no fly for the double-set triggers, so no half-cock notch. The tumbler doesn't appear to have ever had one, either.
