I try to find components that are of the exact same year as the bicycle I am Street Restoring. A Street Restoration, by the way, is one that my limited budget can afford. A Street Restoration get ridden a lot. Anyway...

I have owned a few "as sold" 1975 and 1976 bicycles with full 1972 Campagnolo components installed right from the bicycle factory. My theory is that Campy, in answer to the early seventies Bike Boom stepped up production in 1972 only to experience a sharp decline in sales for the next few years. Some manufacturers, such as Mondia and CCM might have purchased a lot of left over Campy stuff to be used during the mid seventies years. So, is my 1975 CCM "Tour du Canada" period correct? It was sold new with 1972 Campy components.

And, then of course, there is the aftermarket thing that will play havoc with anything that is to be thought original. I like a Turbo saddle but I am not the least bit interested in buying an remanufactured one. If I want new, there are much better saddles out there in today's bicycle world. Again, just an old man's opinion.
