Oops! Forgot the rest of it. Bolig lists the 1907 Quartet version on 96000 at 76.60 rpm, and the 1908 version on 96001 at 80.00 rpm. On the other hand, the 1908 version of the Sextet on 96200 is listed at 78.26 rpm, while the 1912 version on 96201 is listed at 76.60 rpm. So Speed 82 would not work properly in iehter case. Howard
