Well kinda solved. I went along with those of you who opined
that a 1903-1908 Colt Pocket Hammerless might fit the holster.
First I looked on Gunbroker. They have quite a few, but any that
I would consider would be a grand or more.
Another consideration is I would not carry a .32 or even a
.380 for personal protection unless it was all I had, and it's
not.
I may be crazy, but I didn't think it would make sense to pay
a grand or more for a gun to see if a $25 holster would fit.
So then I had this great idea. I remembered a cap gun that
Hubley made in 1940. Dimensions are practically the same
as the 1903-1908 Colt. It even had the rampant pony, but
I have read that Colt made them stop using that.
Here it is. It fits real good. I had to lengthen the strap
about a half inch and the plastic grips were slightly warped
but that was an easy fix.
