Kimball made two models that played paper rolls that were arranged and
cut for their organs.  They were the Model 500 series and 1200 series.
There was a Model 500 on eBay a month or two ago.  I have one, a 500,
and about 60 rolls.  The organ is not worth rebuilding, so I plan on
using the player in an organ I started years ago using Devtronix
electronics.

The only Thomas and Gulbransen players I know of used cassettes, not
paper rolls.  I worked for a dealer repairing the Kimball, Gulbransen
and the occasional Thomas.  That was back in the 1960's and 70's.
I hope this helps Kermit.

I'm always looking for rolls.
