The Siemens ones are 20 amp, Type QP, single pole. 1 inch wide. Installed but never used. Initially bought with a new Service Panel, ran out of room in the panel during construction and had to replace them with half width ones to make room. $3 each. Have 4.
The "Zinsco" ones are "GTE/Sylvania 40C" ones. One is 15 amp, Normal width (11/16"). $20. The other is 30 amp, half width (2 in the 11/16" width), double poled. (Says "Type RC38AL" on the side.) $30. Working pulls, guaranteed good.
The small side panel is a Federal Pacific. It contains two double-pole breakers, one 30 amps, the other 40 amps. Box dimensions 5 inches wide, 8 inches high, 3 1/2 inches deep. Used, guaranteed good. $40.
