Actually, I got one thing wrong. My original brief illustrated essay on telling 50s from 70s isn't gone. It's still here:http://www.vintagedrumforum.com/showthread.php?t=42035And I have little excuse for not checking. Even the searching has been restored to good health now that we have gone to a stable vB3 version (as opposed to vB5 which belonged in a stable ;) ). Yippee. But I still do have an amended version underway.
