In my documents about Symphonion discs 13-5/8" (34.5 cm) I have found
the following numbers ending on -42:

  6042 Praise ye the Lord, Choral, Joachim Neander
  6142 On the beautiful Blue Danube, Joh. Strauss
  6342 Jolly brethren waltz, R. Vollstedt
  6442 Columbus, March by C. M. Ziehrer

I could not find other discs.  I am sorry.

Musical regards,
Hendrik Strengers
