My serial #, just found it, is on the seat tube, to the drivetrain side and below the seat stays. It says, GN4076. There's nothing on the bottom of the BB. Actually, the sticker says, "Manufactured under licence, by Gazelle." I'll have to do a little cleaning before I can see anything on the spindle. So these tires aren't tubulars? Thing is, it looks like the tires are different, but one is a Kenda, Made in Taiwan and looks fairly new, so I didn't even think that these were sew-ups...wow, new level of complexity.
