Tradebit is legit. I bought a few from there. Ebay has digital downloads.
I have purchased manuals before and I try to google the place that has it for sale. If I find at least one other person on a forum that says the site is OK, I buy it. So far so good.
And we have the same tractor, just a little newer.
I need a manual for a 1956 Alco S-6 Diesel Electric Locomotive. Google that and the fist zillion hits are for HO scale.
