I found a Slazenger Vilas Pro racket that was my brother in laws. This racket was never ever used it sat in its cover for over 25 years. I'm looking to restore it. The grip was literally turing to dust. What I'm wondering does anyone know the specs for tention for the strings on this racket. In my research I have seen that the Vilas Pro and the V-24 were basically the same racket one was maroon one was purple I think they came out around 1982-1983. Does anyone know what the string tention specs are for either racket?
