I have a test roll for 88-note player pianos that I really like.
The box is labeled "Universal Player Piano Company" on the box
cover.  The roll leader label is "Playrite Test Roll T-1".

I think it has the best "maximum demand" section of any 88-note
roll I have.  I'd like a backup spare just in case something
untoward happens to my copy.  Does anyone have one available?

Thanks!
