Gunsmith tools of some kind. Came from an estate of a Colt SAA enthusiast. Threaded tool is marked "13/32 to 7/16", $32 all three shipped.

Chrome or nickel Colt SAA 44-40 barrel. I sold this on eBay and it was returned. Customer said that the threads have been modified to fit a different generation of SAA. It is beyond my area of knowledge... good project barrel $48 shipped.

Well, the marked tool is an adjustable reamer, though at that size I'm not sure what gunsmithing it would have been used for. No idea about the other two, the one with a closeup of the end looks like a field-expedient solution of some sort.

Do you know the TPI on that barrel? 20 or 24

I'm sorry I don't know and have nothing to screw it into for a reference.

The threaded tool appears to be an adjustable reamer.
