OK here is what I have been able to figure out . . . and it is not much!
I'm breaking the manuals down into 2 parts, the USER/OPERATORS manual and the PARTS manual:
CURRENTLY I have the following for anyone who needs them:
- 1963 Users & Parts Manual, including a Gas Heater manual (59 pages)
- 196?? Parts Manual, no gas heater information (21 pages)
- 1972 Users Manual (contains some 1960's drawings!) (30 pages)
- 1972 Parts Manual (contains some 1960's drawings!) (50 pages)
- 1975 Users Manual (contains some 1960's drawings) (46 pages)
- 1975 Parts Manual (contains some 1960's drawings) (56 pages)
I have a couple other members who are lending their manuals for me to copy, I will get them digitized and let you all know what they are.
I would have no problem sending you all the manuals on 1 CD-Rom Disk if you want all of them. Or if you have a Snow Trac from the 1960's I could send you just the stuff from the 60's; and if you have one from the 70's or 80's I could sent you the manuals from the 70's. Your choice.
I do not ask for any payment for these, as long as I am only putting them on a CD-Rom disk, disks & postage are cheap. As members are lending their books to this effort it seems unfair to charge.
But I do ask you to participate in the forums! 
Please post some of your photos, please comment on other member's work, problems, etc. Please ask your questions here. By my estimates we have almost 30 Snow Trac/Snow Master owners who visit this site, many come here every day, but only a handful of owners actually post information. We need a little bit from everyone so we can all learn.
If you don't know how to post photos or start a thread, please send me a "private message" or an email and I will help you get started. Photos have limits and may have to be resized, I can do that for you if you have problems with photo editing.
