If you take into account what it states underneath the box where you enter the serial number. And it should say "This tool sometimes works".
Notes: This tool works for Schwinn bikes from 1948 to 1982. All serial number records before 1948 were lost in a factory fire.
This is also very incorrect, actually it's completely false. Dumb informing the dumber. The dates associated to the serial numbers is the date the number was stamped on the bike's component prior to it being used to build a frame.
The serial number on a Schwinn frame will tell you the date that frame was manufactured.
