TOURETTE et BUISSON
Isidore Tourette practiced in St Etienne from 1835 to 1850 (Stockel); he filed patent no. 6878 on November 24, 1834 (with addition of May 19, 1836) for a percussion rifle loaded by a pivoting breech. This is accessible after turning the large key that advances the barrels.
I also find a patent dated January 15, 1836 in the Who's Who.
He then improved the system for dismantling the barrel by patent no. 7573 of September 14, 1840, this time under the association Tourette & Buisson.
The rifle presented is of this type.
Caliber 20; total length 1.22.
Barrel in curled Damascus.
Butt plate with access hatch containing a chimney disassembler and a capsule box.
The strange marking that you can see on a photo is a mystery: all the coins are struck with it (including the wood) and it is obviously not by a marking truncated by a bad strike.
There is a hypothesis concerning this marking, apart from one possibility (to be verified): there were apparently quite a few controllers of Hebrew origin, and they marked in old Hebrew (??)
