Early Westinghouse "Aeriotron" WD-11 Vacuum Tube
Introduced in 1922, This Aeriotron WD-11 Vacuum Tube manufactured by Westinghouse was one of the first tubes used in home radio receivers.
In 1923 the WD-11 was supplied to RCA for use in receivers and the name was changed to Radiotron.
The WD-11 was offered for general sale over the counter in 1923.
CAUTION: The 1.5 Volt filament can be easily damaged by testing with an OHM meter.

Cooper Hewitt Rectifier
Mercury arc rectifiers were also known as Cooper-Hewitt rectifiers. They provided DC from an AC source as an arc between a pool
of mercury and a metal anode. They only allow current to flow in one direction.
This Cooper Hewitt Mercury Arc Rectifier was made by Westinghouse around 1921. It's their model number 222324.
It's rated for 10 amps at 125 Volts.
List price was $11.00 in 1921. This Mercury arc rectifier is 13 inches tall and 9.5 inches wide.
