Jack Kramer Staff info and help

[dirkgnuf]

Hi, I recently visited my cousin's house and noticed a old wilson racquet. Low and behold it's a Jack Kramer staff, butt cap says AWO/AWQ? anyway I was wondering what kind of string and tension is reccommended for this racquet, and since this racquet was bought in asia(cousins live in thailand), it does say midsize, but I am curious what the head size is.
Thanks
