I should be able to make this available, possibly as early as the end of next week?!? This version shows hydraulic control operations and is full of hand written notes that many may find helpful.
Gary also sent me the Parts Book for the Snow Master. It includes the hydraulic diagrams.
I don't have these books dated yet, but I suspect they are late 1960's? They are the big wheel versions. I am hoping that Lyndon can give us a better indication of the dates so I have posted scans of the cover of the instruction book and the first page of the parts manual.
