a very heavy six-shot-volley-pistol “one hammer releases
all six shots”, cal. circa .34 percussion, the barrel
cluster and system are mottled brown, the grip is plain.
After cocking the hammer, pushing the front trigger and
pulling the center pin the 5” barrel cluster can be pushed
from left to right out of the frame for loading/unloading.
There is no maker's name, no proof stamp (therefore not
Belgian or British made).
It appears to be a simple forerunner of the French Jarre
harmonica pistol.
Made during the high days of percussion ignition during
the 1850 - 1860s period.
One can call it a prototype, in good working order and
fine condition $5,000.
Nice old stuff there.
