I am an avid collector of wood rackets primarily, and buy, sell and trade them all the time, I do some cleaning and restoration and "de-warping" work on most laminated wood rackets from 1930 to the last ones about 1986...I also recycle them and make custom fishing nets out of them, and relaminate them with extreme exotic woods from all around the world ! Since I have carved open over 2000 frames from most manufacturers all over the world, I have a very intimate knowledge of their construction and quality. My collection has, at times, numbered up to about 5000 woodies....Happy to share info....
