Picked this up at a gun show. I have been looking for one and there it was. I have wanted to add this to my small collection. It's in pretty good shape. It even still had some of the old cosmoline on it. Whoever had owned it either didn't use it or didn't clean it up.
Camillus made these continuously from 1957 to 2006. Some years are harder to find than others.
The 2006 marked knives tend to go from $60 to over $100 dollars.
Usually I'd say most examples can be had for well south of $50.
There are examples of some particular years going in auction for around $300.
Different makers of these metal scale knives start showing up by 1944. Not all are dated. Lots of opportunities to spend your money acquiring different ones.
