I spoke with a fellow that worked at Michaels cyclery today, and asked him about the Japanese 531 Raleigh frames they sold back in 83. He told me that the red ones were Internationals and the blue ones were Competitions. He also told me that they sold around 500 of those frames. Apparently the Suntour dropouts had a fairly high failure rate, so keep an eye out for cracks if you have one of these frames. He remembered them selling for $150.00.
