I have picked up the above frame to build up for a commuter bike. The only thing I have found out so far is that it is a pre 1975 frame from Japan, there is a sticker that says Chrome Molybdenum, another stiker says Kokusai(model?), the serial number under the BB is KS86955 with a W beneath the number. So I research & found out the maker is Wakamura. Would like to know more about these bikes/frames? Are they high/medium/low quality bikes during its time? I want to know if its is worth restoring or just put minimal parts on it to make it ridable. I will post some pictures later. Thanks.
