Dynaplate Radio Telephone Grounding Device

Aquadynamics, Inc., No. Hollywood, California

Eliminates copper sheet installations...Pure Gold-Plated Terminal Bolt assures perfect contact

Magic Silver Solder insures maximum conductivity.

A quality product using bronze and precious metals.

This item has never been used but I think the pure silver solution is dried up, it could still be useable but I am not sure.

Instructions are located on the back of the plastic case that it comes in.

The block measures 6" x 2"

This item was patented in Europe in 1963...Maybe just a collector's item....

Thanks for looking!
