I have the following Schwinn Tempo that is too large for me. I would be willing to trade for something similar (or possibly trade up) for something in the 57-58 cm size. I am partial US, Japanese, Italian brands and 1980s vintage.

Tange Falcon Headset included
Seat Tube CTT 25" (63.5 cm)
Top Tube CTC just under 23" (58 cm)
