700D has a bead dia of 587mm, that's pretty close to 650b. Didn't some GT mtn bikes or hybrids come equipped with 700d wheels- some sort of spec oversight or factory miscommunication- in the early to mid 90's?

Sure it's not 650B? I know Schwinn did use these on some tandems. They _are_ "26 inch" but "26 inch" is _not_ a tire/wheel size. It refers to one of at least 5 _different_ sizes.

See: for the detailed poop on this.
