The front swivel looks to have been ground off????

It has the proverbial V-C Stop.

Canons Gallia was a marque of Berthon Frères....

>>"Berthon Freres" was active from 1893 to 1922.
Their catalog included the "Helice-elite" (sic) brand and the "Gallia" brand.
"Gallia" is of course a play on the Latin name for what France was way back...
The preceding structure was "Martin Gerest" and the following one was "Laspoussas Berthon" followed in '23 by "Laspoussas & Driol". The "Berthon freres" brand could have survived until the 1950s...<<
