I was at a garage sale where I bought a woodworker's entire library of Wood Magazines (#94-200), woodsmith and shop notes magazines and a ton of books and plans. ( SCORE
Buried within all of the magazines and such I found the following collection of Shopsmith Documents. The Manual has a revision date of May 1981.
I thought maybe one of you restorer guys might be interested in this set of documents to complete your restoration.
PM me and we will work something out to get them your way.
Take care,
Geo
