Unless it is really early, such as the one that was a bin under keyboard,
all Link pianos used the same spoolbox.  They had metal sides and a brass
tracker bar.  There was a heavy steel roller that sits on the paper to
provide traction for the rubber roller to pull the paper.  They were well
made and did not have a home made look.

Mike Walter's roll with the arrows and fifteen tunes sounds like a Link
roll.  None of my original rolls are playable, unfortunately, and are
grayish in color with the arrows every three or four feet and tune
number.

Link pianos have a unique sound that is very lively and pleasurable.  It
took me quite a few years to actually own a Link piano.  I have the Link
C that was pictured in Treasures of Mechanical music.  It is unrestored
but still plays well.  Changing the roll is not as easy as the rewind
type but the music is worth the effort.

Link pianos are still a favorite with collectors today.  I have the a
spare set of center panels for a Link C if anyone needs them.  I got
carried away and paid $1000.00 for them years ago.
