one being beethovens op 130 quartet in b flat major perfomed by the lener string quartet dated 1929 ax 2256 and also i have beethovens op92 symphony no 7 in A major performed by the new york philharmonic orchestra and conducted by toscanini d.b 2986 dated in the 30s of hand i think without
checking the album. in particular is the quartet rare as one web site suggests and others dont give much detail or infomation
