I Heart Thomas Muster,
Unfortunately, we do not have any more Muster racquets coming up for sale at this time. We found that racquet in our Bosworth collection. We haven't gone through the collection completely as it is mostly boxed up but from time to time we will go through and see what we can find. So don't count out finding another one completely.
As far as specs go, this is what we had on the one that sold:
Grip size- 5
Length- 27 inches
approximate strung weight- 13.4 ounces
string pattern- 18x20
head size- 93 sq. inches
