A friend of mine has lost a knife that his father left to him, a Camillus "Monroe Hardware" advertising knife 1971 or 1975 version (he wasn't sure). He asked me if I knew where he might be able to acquire a replacement. I was wondering if there are any Camillus collector groups or companies that may be able to help him out. Though I have a number of Camillus knives, I am no expert in them and would appreciate any help.
