[Superscope]

It's unusual not to have a Date Code on these, but it does happen.

It may possibly have had a New Movement at some point.
Serial Numbers or bits of, are often neglected on New Movements.

I looked up the serial No, and it points to 1967, probably around Aug/Sep.
A new Serial Number Range started in 1966, hence your relatively low
number.
This of course assumes, the Serial No is correct and no numbers are
actually missing. If the number was (1)2260, it would be late 1971.

Nothing is guaranteed though, in the Avo World.
