It is an old Spalding racket with a frame made from a solid aluminum beam (not hollow aluminum like some later rackets). The head is standard sized which I guess is about 65 in.^2. The head measures (from the outside of the hoop) about 9 3/4" width x 10 1/2" height (nearly round). It has 64 string holes in total. The overall length of the racket is 26 1/2". I can't find any text on it that identifies the model, only the manufacturer.
I would also like to know if anyone knows the string pattern and recommended string tension for this racket.
are some [poor webcam quality] pictures of the racket.
