The serial number on the OP's frame, K605369 is a Japanese serial number.
The frame was made by Panasonic in October, 1986, as a 1987 model year Voyageur. The assembly date code, 3496, indicates the bike was assembled on the 349th day of 1986 (mid-December, 1986).
I would be shocked to learn that Schwinn broke a very important trade law by selling a bike made in Japan without clearly marking the bike as made in Japan. Every Imported bike was clearly marked.
