Anyone collect Case knives?

[LostInTheWoods]

Just wondering if anyone collects Case knives, and what the best source is for appraising them. I have looked for a good internet source, but can't really find any. Any good books you'd recommend?

I collect the Schrade Walton that were made in the USA. I have bought several off Ebay. Ken Sweet
