While I'm not 'really' old, I do remember those pot metal "cap guns" that many kids played with "back then".
A neighbor-friend stopped me on the way to the mailbox and wanted to show me something. (He's a not really old guy too.)
He went in his house and brought out a shiny pistol that turned out to be one of these old cap guns. It was a revolver (cylinder rotated with DA trigger pull).
It was ornately decorated pot metal fit together with screws and pins. It uses the old "roll" caps that feed up through the hammer.
He was smiling like a us kids smile when new toys show up.
The guy that started this business assembles the parts and sells them in a number of "Old West" versions of derringers, six-guns etc. He's also an old west buff, and has many of the old classic western movies on his site. His phone "ring" is the theme from the Lone Ranger.
