For sale is this GREAT Teleconcepts model 100 Periscope rotary telephone.
This is a great conversation piece, and has been tested and it does work! There are only a few scratches on the base, and the chrome is in great condition.  The inside could use a good cleaning with some plastic cleaner, and there are screws on the bottom to get to the inside parts.  All in all in very good condition with no chips or cracks to the lucite.  The phone stands 17" tall and 7 1/2" across the base.
