Help on dating my new (old) Schwinn Twinn Tandem
I found the number stamped on the left dropout, but then noticed this number did not correspond with any of those i found posted on another thread of all chicago schwinns. it is from the chicago plant, as the original decal on rear seat post shows, but the serial number seems to be #OC50005. i found that #CO50005 was made in 1960 (3/31), but i could not find any which started with an "O" . . . puzzled. any help would be appreciated.
by the way, it's royal (or sapphire) blue and a beauty, w/original everything, it appears. diggin' the big 26" whitewalls!
