Henry Smith? Too bad the name is so common...but the name of the "Texas Invaders" is well known. May 19, 1892...we know exactly where Henry Smith and a fancy Pearl handled Colt was if I am readying that letter correctly.
"41 Caliber 4 3/4 with Pearl Grips
Shipped on April 7, 1892 to Munkres and Mathers in Buffalo Wyoming."
I'd be wanting to know what happened to Mr. Smith.
By your letter the town Marshal, Mitchell, disarmed Smith at least once by my reading, may be twice in a few short minutes while Smith was in possession of that same pearl handled gun. Eventually Smith made it out of town with his guns (again by my reading of the letter) with the pearl handled gun still in tow.
I believe Henry Smith, by his own word admitted bush wacker and killer, was the first "owner" of your pearl handled Colt.
