I have a early 68 and I am trying to find a manual for it, but everything I find is second or third edition. Does any one know if there was a first edition 68 manual or or did they use a 67?
The "first edition" was printed in August, 1967 and is P/N 3927528. I believe the reprints are the third version (P/N 3940153), but I'm not positive about that. They may be the second version...
Keep checking ebay and when you see one, email the seller and ask what edition and P/N it is. The reprints don't have a revision level.
