I have two copies of the 1921 Duo-Art Test Roll.  This test roll is
also known as "Test Roll #2".  One copy is mint condition and the other
was used to the point that a new leader was added.

I bought them from the estate of an old tuner and player repairman
along with a pile of tools and other stuff.  I would be happy to make it
available for recutting if someone gets a Duo-Art perforator running.
