Note
Radio magazine, Jun 1937, p. 84.
Dot stabilizer, main spring, and dot-dash contacts may be purchased separately.
Contacts are 3//16" "fine silver" mounted on 1/4" fine threaded screws.
Finger pieces are Bakelite.
All parts above the base are chrome plated.
Base is one-piece cast (does not say what it is cast with), "now breathtakingly gorgeously finished like a piece of polished black marble with light veins running through it."
