I have been trying to find information on what I believe is a French patented pistol cartridge, with the number 81-00-841, but I haven’t been able to find anything anywhere, and I tried the INPI website (Institut National de la Propriete Industrielle), but to no avail. The original French text from an article reads: [quote]Cette invention est brevetee la requete en demande de brevet a l’I.N.P.I. deposee le 14 janvier 1981 a eu comme notification de numero d’enregistrement national 81-00-841[/quote]
Which I took to mean that the cartridge had been awarded a patent or registration number of 81-00-841 in 1981, but I can find nothing on it. It was for the ALIA steel core pistol cartridges and this information comes from the July 1981 issue of AMI which had an an article on ALIA written by Andre Rolland. Anybody know how these French patent numbers work?
