This auction is for a Half Moon Leslie Switch that could work with the 26-1 connector box to connect a model 145/147 Leslie speaker to an organ which is in another auction.  It was for using with a model A100 or any other organ with internal speakers.  It has a 5 pin plug attached to it.   It is used and worked the last time it was put in service but that was over 10 years ago.  I have no way to test it so it is being sold as is.  Buyer pays shipping and handling.  PLEASE DO NOT PAY UNTIL I CONTACT YOU ABOUT THE REAL COST FOR SHIPPING.  Thanks for looking, good luck.
