    An interesting record! I have a record with a similar "blank" side, with a plain black paper label. However the groove is very loosely spaced out like a large spiral, rather than spaced normally like here.

      With regard to the record you mention, is the other side (the recorded side) Side 1 of a piece of music that requires a further record/s to complete it? e.g. a Symphony, Concerto, etc.

      @@anthonythompson8749 It was the last record in a record set of The Young Person's Guide to the Orchestra, which has an uneven number of sides. I only have this last record, at some point the set was split up.

      I'm not sure if this is going to help and you may already know about this.
      When a piece of music was recorded which required more than 2 sides, the music would then be continued onto a further record/s. For example, the 1st record would have sides 1 & 2, the second record would have sides3 & 4 the third record would have sides 5 & 6, and so on, depending on the length of the music.
      With the advent of the automatic record changer where records could be 'stacked' onto the autochanger mechanism, record companies started to issue these record sets as what was known as 'Auto Sequence'. So, with a piece of music requiring (say) 3 records, the 1st record would contain sides 1 & 6, the 2nd record would contain sides 2 & 5, and the 3rd record would contain sides 3 & 4. Therefore, the records could be stacked onto the autochanger so that side 1would play first, then as the next record dropped, side 2 would be played, and then as the final record dropped, side 3 would be played. After side 3 had played the listener would go to the record changer, lift off the 3 records and turn them over. Re-starting the autochanger, would mean that what had been the 3rd record would drop first, paying side 4, then the next record would drop, playing side 5 and finally the last record would drop playing side 6.
      In your case the music required only 5 sides. In some cases, what would be the 6th side would contain a shorter piece of music only requiring the one side. However, this did not suit everyone's taste. Therefore the 6th side would sometimes be made with this spiral groove, as you mention. Thus, if playing the records on an autochanger, after the 5th side had played the final record would drop and the pick-up arm would simply be moved within a few seconds to the end of the record, the autochanger would then stop and the 'record stack' could be removed.
      The standard number of records that could be stacked onto an autochanger at this time, was 8. Therefore if the work required more than 16 sides, further records were issued in a further sequence.

      @@anthonythompson8749 I knew about the autochanger sequencing, but didn't make the connection with having the spiral groove so the changer completes the sequence. Strangely though my record is side 5, so the record set wasn't in the auto sequence. They must've used the spiral groove as a default blank side so in auto sequence sets it keeps the changer running and in the ordinary sequence it won't do any harm.
