Sand - if you'd like I can translate the catalog entries for you. Both the entries for Heliduplex and the entry on Helice-Grip. Mostly of it is advertising hype but it might give you an idea about the history of your gun. Also, you might write to the factory on the provenance. French people can be most helpful (outside of Paris). (and if you tire of it..please let me know).

Baluch are not Brahui, Brahui are Baluch
