No, I'm not 100% sure they're 650B. The sidewall reads: 26 x 1 5/8 x 1 1/2
No shop or catalog seems to have such a match, and since the only tires I have lying around are 700c at the moment, I can't test fit any 26'ers.
I did perform Sheldon Brown's wheel-size circumference test (measure bead-set circumference, check on Sheldon's chart) and my 72.2" measurement lands right on the 650B.
The frame is a DBS (Der Besse Sycle or something like that, basically translates to The Best Cycle). It's a Norwegian "Huffy" from what I've read. Straight, non-tapered steel tubing, many aluminum parts -- rims, spokes, fenders, hubs, full chain guard, even the front drum brake -- and a sweet pump drawer on the chromed steel rack. Single speed with coaster in the rear, and a drum on the front.
