Now you can build your own Wall Communication Unit.
This back piece is made from Celtec Red Plastic and is cut to exaction dimensions. The large hole is designed to fit the Honeywell original style red button switch. (This is the original switch used on the show). The black bezel with white dome switch is designed to hold the "Heatherington" recreations. They fit perfectly into the hole.
I sell the blue comm unit and the resin beacon that attaches to this unit. Heatherington recreations are sold on ebay from time to time as well as the red Honeywell switch.
Shipping is 8.00 due size and not weight so much.
