Where and when was my Schwinn Traveler made?
The serial number is for a Japan manucatured Schwinn.  The serial number format is Bridgestone.  "I" is for the ninth month(September) and the first digit, "6" is for the year of manufacture 1986.  This matches somewhat with the headbadge date of day 022(January) and year 7(1987), which is supposed to be when the bicycle was assembled.

Schwinn must have used more than one Japanese manufacturer, including Panasonic.
