Please read remainder of post before posting "do a search"!! I have recently been talking with BF member who has some old YY rackets,sourced from JP. They are old, maybe 1980-1990. The thing is they don't correspond to the racket coding we know as current & they also don't have the JP code on the shaft. Why is this? Current rackets have JP encrytions, did the older rackets only have country coding for exports only. I have seen 1990's rackets with KR & CN codes, but not JP. Please help!
