'schwinn tubular s-7'

I have an old front rim stamped 'schwinn tubular s-7' . Can you tell me what period is it and what Schwinn models use this rim.
thanks

They started using them around 55 on the middleweight bikes, I know they went through the 70s.

They only take 1 size tire by the way.

Yes, the 1 3/4" is always the S-7 size, 1.75 is standard. They used the S-7 through the last Typhoon and Hollywood models in 1982. -Adam
