If you're going to list Mercedes Benz, you ought to list Porsche (yes, made by Volkl...I believe it was the Vario 5 or 6)
I once played an Australian guy who had a bagful of Symonds or Symmons frames.
I know you've got it listed, but I thought I'd mention that Pat Cash used Stellars before Slazengers, Prince and Yonex.
Swing Tip (cheapo junior frames in the mid70s)
Avery, Tom Avery.
Lennart Bergelin had some frames made, most notably, the Bergelin LongString.
