Here's something that's a truly rare find!  This is an original DeArmond Rhythm Chief 1100 that is in new condition in the original box with all of the original paperwork and the original cable. 

This one dates to 1963-1965, based on the unit and the materials packaged with it.  It looks to have been carefully stored over the last 50 years with minimal wear to the box and no discoloration of any of the items.
