1959 is the only Canadian AMCs that I know of, I do have notes that I don't recall making about a 1966 Canadian version. Depending of course if you classify this one as a model circular or a catalog.
Don, I got the feeling you read all the posts on catalogs, there may be one or more you missed in the collectables forum last month. Although you don't need to read it now as you have one, great find, good spotting, well done. You guys don't realise how good you have it, model circulars and catalogs at gun shows and collector meetings, something I have never seen in Australia. You cannot believe how much I'm looking forward to attending one of these collector meeting and some US gun shows.
