This has a "new" model saying 1979 I can't seem to find the exact date of this catalog, however I assume it was printed in 1978.
It has specifications of equipment, shiny cover, and a bit of audio electronics of how they make things work.
There is also a few pages of a large amount of old FM radio stations, call letters and locations, I am sure many of those stations are gone by now, kind of a cool thing too see.
The back cover, and a little on the front has yellow areas, it didn't get wet, I see no leakage on the inside of the cover. Also has some dents or not 100% smooth and flat (see pictures).
I would say fair to good condition, no rips.
it's a good read even though it is a "product" catalog.
