Vesailles: Here is my analysis of your barrel flats; photo is unclear; It is Saint-Etienne. I don't know what the three balloons are but might be a manufacturers' proof mark. Where I think where the Fanget mark is (need a clearer photo) there should be some other sort of advertising bits. I'd have to research "Helios"... You didn't give us much to go on.

Here is what fab500 posted about the original gun:

"SOLYD was a copyright of SMFM (Saint-Etienne)(Société Moderne de Fabrication Mécanique). This company was created by Rouby-Montuclard in 1945. In 1950's they made an electronic action which were not a great success."
