Tom Threepersons' personal holster -- and the only one
Recently I acquired Tom's own holster, and it fits all the criteria that we know today as a 'threepersons' style holster, including the welt design that retains the SAA without a safety strap via a tapered, double-thick wedge that today we call a 'welt'.
It restored nicely and its condition is one of a 50 year old holster -- but it's 100. Its unusual construction was used only by a maker known as A.B. Egland that operated in Douglas, Arizona -- which town, according to the A.T.F. (the only one of 5 agencies he worked for that claims him online), was Threepersons' first appearance at rodeo in 1916.
I acquired it from the widow of Fred Wells, a noted rifle-smith in Prescott, Arizona, along with its provenance documents. This acquisition led me to a thorough search about Tom and I was helped along the way by crazyphil and by turnerriver. Here are two pics:
The documents shown come from the A.T.F.'s website, which is the most thorough of those I've seen because it omits common errors (he was neither a Mountie nor a Texas Ranger) and admits what it doesn't know (his birth is reported variously).
Apologies that the pics are upside-down, because they're right side up before loading! The belt is not original to the holster but is equally old: A Heiser in 38 cal (Tom's was .44 W.C.F.). And the revolver is a Nichols (no relation) capgun from 1960, cut down to 4-3/4" (standard is 6-1/4") that is surprisingly on-size. And those aren't rubber bands holding the set in place; it's leather lace.
