Some of the rolls I've acquired are pretty badly treated and mis-filed.
The latest of these is a setting of the Blue Danube Waltz with no
label on the leader.  It doesn't seem to match any of the MIDI files
from the other "Blue Danube" rolls that I can find on the Internet.
There's no expression punched into the roll.

The two bits of info I have are the music [MIDI file transcription of
the unknown piano roll], found at

  https://docs.google.com/file/d/0B4hP8q2bof1VQTRobjVxSE5ZcmM/edit?usp=sharing 

and the printing on the leader, which you can see at

I'm hoping someone might recognize the leader printing and give me
a manufacturer's name to go on.

Thanks,
Marshall Jose
