I believe he uses the word "Founder" to imply it is in very good collector condition. Nothing more. I have and still do buy from him off e-bay where I'm looking for a particular item to complete a tool. Sometimes he has reprinted catalogs that interest me. Nothing from him is a great deal. If you go to sell it, because of taxes and possibly listing fees, you will need to hold onto it for a number of years and hope the value is still there. For me, what I buy will add value to the tool I'm working on. So, I hope to do all right. I have no exposure directly with the man.
