Maybe not the first couple model years, but probably 68-69-70ish. In the 70s they started moving knobs around.

That is a very good point. 1974 is a guess based on chassis numbering, N-1 and N-2 were 16" sets just a step up from porta-color and they were introduced in 1971.
The channel knob type on this set was first used in 1966 IIRC but those flat knobs the squirrel refers to were more common on the 1970 and later 16-19" sets.
Of course Im going by a few brain cells myself, probably compromised by all those griplets I soldered on the later small-screen GE's
