[Vintage-Radio] Key set

[Avery Comarow]

Before putting this interesting gizmo up for sale, I'd like to know more 
about it. It has a good-quality brass key, a separate switch with big brass 
contacts, and a buzzer, all mounted on a finished wood base, equipped with 
bumpers, about 8 inches by 12 inches. At the far end of the base is a 
connector block with many openings. Three pairs of the openings are labeled 
(stamped into the wood base) BAT., OMNI., and TELO. A metal plate 
identifies the manufacturer as Century Telephone Construction Co., Buffalo, 
N.Y.

I'd appreciate any information, and if someone is interested please let me 
know off the list.
