content: Marked: (tube socket plate) "Receiving Tube Socket / Signal Corp - U.S. Army / Western Electric Co., Inc. / 203A"; (nameplate): "Westinghouse Electric / & Mfg. Co., Pittsburgh, P.A. U.S.A. / No. 1146627 Ser. 321497". Specimen, though lacking a military type letter, appears to be a Signal Corps receiver of the WW I period employing a 203-A tube (missing) as a regenerative detector. Coupling between primary and secondary coils is varied by a swivel control on the primary. Regeneration is varied by changing the tickler coil setting with a panel control. There are two sets of multipoint contact switches for the primary and one for the secondary. Wavelength range appears to be 500-1200 meters. The secondary condenser has a 0-100 logging scale. Binding posts on the panel provide connections to external batteries. An antenna switch is include in the case.
