i would have to see the pictures on the inside of the manual to determine if it truly is an original copy. i still have a few of these 70.3 manuals left, i used to sell them as repros, because that is what the ones i was selling are. an excellent repro copy, but the pictures in this repro manual are not as clear as pictures in original manuals.
can't seem to resize pics from my phone to get them in my computer, otherwise i'd include pics of the manual i have which looks as bright and shiny new as the manual on ebay.
