There was a time when FPKs showed up at least half a dozen times a year during my rounds of local GWs. Not anymore. As I was not a fan of their gaudy makeup, I kept putting off taking one home until they vanished from the shelves. When I came across this lightly used example today at a Salvation Army store, I figured it was likely time to surrender to the inevitable. After seeing its butt cap code, any reticence towards full capitulation evaporated instantly.
The stamp is unmistakably "BSQ", meaning this racquet was made in 1989 alongside those PS85s from the mythical Sampras hoard.
Until today, I have never seen an FPK that was not made by SanHoSun. The overwhelming majority of "FPK" butt caps are stamped with "SA_", indicating SanHoSun manufacture in 1988. A few were stamped a year later with "SB_". If this "BSQ" butt cap is original to the frame (and I really can't see any evidence that it has been tampered with since leaving the factory), it is evidence of a highly unusual instance in which St Vincent produced a racquet (in relatively small quantities?) that was FIRST made in Taiwan! What was there for Wilson to gain by doing this, considering the increased labor cost and logistical complexity of partially moving the production to St Vincent, against the flow of their other project migrations at the time? It makes no sense!
The paint on this racquet has not turned purple like on some others, but it had seen very little sunlight since birth, so this may not mean anything. The one difference I can see from the SanHoSun-made frames is the square grip size sticker, as SanHoSun stickers are round.
If St Vincent did in fact produce FPKs in 1989, then there should be more units out there. If they produced them in parallel with SanHoSun during both 1988 and 1989, then there should also be some examples that are stamped with "A_Q" or "Q_A". Has anyone here seen such beasts?
