No mate. 7600's first came out in the early 80's, 1981 I believe. Prior to that was the model 760, which is like the older sister of the 7600 and was first catalogued around 1952 I believe. Remington made pump rifles in different models way back to about the time of WWI.
It will depend greatly if buying or selling, however more info is needed as if in box new (NIB), and if it has been handled or carried around as in hunting!
