Bring Back Cap Pistols

I remember my very first cap pistol.  It was a pirate pistol which simulated a two barrel flint lock pistol.  It had two hammers that were controlled by a single trigger and the hammers fell down on square caps you had to put into a slotted receiver.  Because it was so nicely designed it make a good loud bang when the caps went off.  It was terrific fun.  Later I had other cap pistols along the lines of the Wild West revolvers.  They took coils of caps and were not nearly as loud as the pirate pistol.

My pistol looked a bit like this, although I don't think this is quite it.
