This page contains some general information about the 300-series telephone sets, introduced in the 1930s by the British General Post Office (GPO) and made by a variety of manufacturers. Some of these sets, in particular the 328, 394 and 396 models, were used during and after World War II (WWII) with a so-called Frequency Changer — an (insecure) inversion-based speech scrambler. The GPO 300-series was originally developed in cooperation with Ericsson UK and is based on the Ericsson N1015, N1016, N1017, N1374 and N1376 models [4], albeit with a British GPO No. 164 handset. This is the same handset that came with the earlier Telephone No. 162 (the Pyramid). There were models for use with Local Battery (LB), Central Battery (CB) and Central Battery Signalling (CBS) systems. Furthermore they could be configured with or without a dial, with or without a bell, and with up to three push-buttons just above the dial, for a variety of special functions. During WWII, a speech privacy system was introduced under the name Frequency Changer. It was based on the inversion of the audio frequency spectrum, and is therefore also known as a voice scrambler. Telephone sets that were used with the scrambler were quite different from regular ones, but were based on the chassis of the 300-series, in particular the 328, 394 and 396. In fact, when there were supply shortages during the war, regular 300-series phones were often converted for use with the scrambler, either at the GPO workshop or by technicians in the field. Original scrambler phones had a 4-digit model number, prefixed with the letters 'SA'. In most cases, they were fitted with green handsets, to discriminate their lines from regular unprotected ones. They were made of green bakelite, as with the SA-5063/1 shown in the image on the right, but could also be regular black bakelite ones that were painted green as a gap-fill solution. Below is some general information about 300-series telephone sets, that we came across during our research, in particular when restoring the scrambler phones in our collection. More detailed information is available from various websites, some of which are listed at the bottom of this page.
