I appreciate your help and theories. As you said, with possibly fewer than 50 made, who knows what's what.
As far as value - I know that rare does not equal value. I have a James Warner revolver in .28 - only a few hundred were made. The same revolver was also made in .32 - over 9,000 of them. And, the .32 is worth more.
I like oddball guns, and this is one.
