My previously announced project to upgrade the 116-note Aeolian
Organ rolls to fully automatic 176-note format is nearing completion.

 [ https://www.mmdigest.com/Archives/Digests/202002/2020.02.12.02.html 

Eleven rolls will be upgraded.  But I am now stuck as one roll still
has not been located.

I would like to borrow the roll that I am missing.  That roll is
Number 51939, or just 939 if it was made late in production.  It is
titled, "Death of Frederick" from Act III, Scene II b.

Please examine your collections to see if you own this roll.  I will
pay the postage for the round trip (domestic, USA), and give you an
audio recording of the finished upgrade of that roll.

Thanks for looking!
