I have a supposedly non existing 40 LLama in a 1911 frame stamped LLAMA CAL 40 S&W MAX-I-L/F.GABILONO Y CIA VITORIA.It is not shown in any books, gun shops claim it does not exist, and LLAMA wanted to know how I got possession of it and wanted to get it returned.It has slight rust but otherwise in mint condition. Some shops say it is valuable because of rarity and some say it's not because it is a LLAMA.All claim it was never sold or marketed and is not listed in any books found.

My friend has the same gun with receipt from gun show legal company legal buy...why cant we find info on this gun??? My friend does not want to sell but just got interested in values on some of his old toys...
