A while back I picked up an interesting single shot shotgun with a bronze receiver. A little research showed it as a ZULU shot gun.
The history of this weapon goes back to the end of the muzzle loading era. With the civil war¬† ushering in the era of the breech loading metallic cartridge firearm. With large stocks of muzzle loading weapons on hand countries needed a way to convert these weapons to a breech loading weapon. One of the first methods was the Snider or Tabatiere conversion.
By the late 1870‚Äôs large quantities of French converted rifle were on the surplus market with no buyers. A decision was made to convert them to a inexpensive shotgun. This was accomplished by reaming out the rifling in the barrels to make them smooth bore, scrubbing all the original marks off the rifles and then proof them with Belgium proof marks, cut down the stocks to a sporter configuration and removing the rifle sights and installing a front sight bead.
This example is a bronze receiver that was made during the Franco-Prussian war from French church bells that were donated because of the material shortage at the time.
