Looking for some Info

[aberastains]

Hi there, this is my second post. i know this is not perhaps the right forum, but i need some information and it seems to be quite a lot activity in here. I have an old Puma knife that i?d like to know its estimated date of production and value. The blade reads
"PUMA" and "solingen" under PUMA. On the other side reads "n 6320 /7" " and under that it reads " Ges. Geschtuzt /3 ". Blade is about 7", the handle is made of several rings, leather i suppose. It has and aluminium end, and a brass fingerguard. It originally had a chrome coating or something. As you may see i?m far form being an expert. Sorry if my english is not so accurate, i?m from Argentina. Bye
Santiago.
