What does this barrel fit.

[THA]

Purchased a barrel as part of a lot at auction.
Have Googled to no avail.

No makers name on barrel (In the white).

Caliber marked ".45 COLT"

20" in length.
Ejector slot cut for top eject.

Barrel diameter: .960" at chamber end. .640" at muzzle.
Barrel threads: .780"x28
Shank length: .638"

Section under chamber milled flat. Presumably for clearance on the magazine tube.
Stamped "195" on this flat.

Milled 'cross slot' at 1" and 12 1/2" from muzzle on bottom of barrel. Mounting locations for magazine tube?
Rear sight dovetail cut at 16 3/16" from muzzle.
(Measurements taken from muzzle as I don't know how much machining may still be needed at chamber end.)

Provided as much information as possible hoping some combination of the above will be enough to identify the rifle this barrel fits.


Thank you for any and all help!

Let me find my barrel shank list( if I can find it!) and I'll see if it is close to anything.

I can't find anything with your dimensions.
Are you sure it's 28 TPI?

Not exactly.
With my thread pitch gauge, none were a perfect match.
I tried 27 through 30 and twenty eight was the closest match.

Possibly metric?

Yep I'd say it is probably metric... Uberti, Rossi most likely.
You could try contacting their tech departments and they might tell you what their shanks are...
