I have restored / rewritten many of the manuals in PDF Form. They have enhanced photos, they can be zoomed to improve readability, there is an active table of contents in many meaning you can click to go there, and for those I did re-write, they are word searchable.
There is also Jacob Anderson's site where he has currently 39 free videos
and some more extensive repair DVD's that he sells for a modest price.https://jacobshopsmithrepair.com/https://jacobshopsmithrepair.com/youtube-videos/
Equally he does perform Headstock repair and servicing, which you have to pre-arrange. All around good guy and he sells some parts for the Mark 5 / Mark V vintages.
Also on eBay https://www.ebay.com/str/bandsawtirewarehouse
