The Frankenau Purse pistol,
One of the great oddities of the 1800’s were the many ways gunsmiths and gunmakers found to hide firearms in everyday objects. One such creation was the purse pistol, a highly concealable weapon popular among Victorian Era ladies. Often the weapon was a flintlock or percussion lock pistol that was built inside of the purse. Later the purse would be made with five shot pinfire or rimfire revolvers.
The example above is of a five shot 5mm pinfire revolver made by Frankenau and sold both in Europe and the United States. As you can see the revolver is built into the frame of the purse itself. A long trigger mechanism folds out from the bottom of the purse, so that the pistol can be fired with the purse closed. When not in use the trigger folds back up into the purse. The series of holes in the lid serve to allow for the escape of gasses when fired. Today these pistols are very rare and seldom in good condition, as they were pieces that were constantly carried, used, and worn. The example above is estimated to be worth around $5,000 - $8,000.
