The oldest version of the 65 owners manual I can find on ebay, or anywhere else for that matter, is the fourth printing.
I am talking about the very first version of printing of the 65 Mustang owners manual released with the earliest 64 1/2 cars.
If you look inside the front cover of the owners manual it tells you which printing it is.
