I remember those things. Vaguely.
I had one of the ones they sold that looked like a Colt Buntline. I think I paid $3.95 for it, and take my word for it, they were a POS. At least the one I had was.
But, when I see Hubley cap cuns going for $100 and more, some much more, who knows, you might have a treasure.
