Fall, 65 mm chambers - 2 1/2 inch post 1912.
last year we discussed a beautiful Heliduplex Verney-Carron...it led to our creation of a Franco-English gun dictionary. In that Heliduplex line I translated parts of a 1920's VC catalog. I remember the page that discussed "Acier Diamant" but am not sure I ever actually translated it.
Take a look at this line. It might answer some questions (and it has our usual on-going discussion about the Saint-Etienne mark "Helice" on a key). I'd be willing to go back and take a look at the catalog page discussing VC's steel... except I'm of the impression that it was pretty much standard advertisement fall-dee-rah.

https://www.gunvaluesboard.com/i-have-a-....-18073018.htmlI have a Double barrel shotgun that has french markins on it. Some of the markings I have found the meanings and others I have not. I hope that you can help me.. It has RB4165(serial number?) on the stock, the barrel, and another pice. The gun also has Champaley Meillier & riou with portee garantie on one side of the barrel and canonniers st etienne on the other side. There are also some ornate markings on the metal. It has an 18.4 CMR also. ANY IDEA? I know that it is French and was made in St. etienne. but i don't know how old it is or what gauge it is.There are references to CMR on French web sites....here's a comment on a CMR barrel on a Francisque Darne on Passionlachasse.com. It's late out here....midnight - back in Africa ...I'll look futher tomorrow.

- production entre 1927 et 38
