Ericsson Other Wall Phones and Intercoms 3
Fig 28: This unusual phone is a French model, produced by Societe des Telephones Ericsson. Although the box and ringer are standard Ericsson designs, the cornet" handset is an unusual style which only seems to have been used in France and Japan.

Fig 33: PMG Type 37 / 137 Auto Wallset . This phone was developed in Britain in the early 1920s to be the British Post Offices standard wall phone, as their Tele 21. It was manufactured by British Ericsson (by now called Ericsson Telephones Ltd) and others for export as well as local use. This was the most common small box set used in Australia. It was designated APO Type 37 with solid back transmitter as shown, or Type 137 with the bakelite inset transmitter as shown in Fig 34. Note the basic stamped steel transmitter bracket, as used in the later British Ericssons. The earliest models may still be found with the No. 8 or No. 10 dials, which are finished in oxidised black and have a smaller centre panel. A convertible model can be found with a steel plate mounted over the dial hole. This was also issued as the CB version.
Fig 35: Type 237 converted to
the bakelite handset. Many of the 237s were made from converted bell boxes , an emergency
measure during World War 2. A CB model was also made. Phones were also converted to bakelite handset
operation when they were reconditioned, but the numbers that have survived with
the older bell receivers suggest that they were an extremely reliable model. Ericsson
catalogues do not list a handset model like the 237, and in Australia the
bakelite handset was an Australian Post Office conversion. These models are therefore
an APO phone rather than an Ericsson. A typical British bakelite handset model
is shown in Fig. 39 - note that the different switchhook has the handset facing
inwards to the phone.
These pictures show similar Ericsson models produced at Beeston.
Fig 37: The automatic model , also with the more ornate Ericsson mounting on the transmitter, was produced as British Model N1050.
Fig 38: The CB equivalent was Model N1450 . Note the simple stamped switchhook for the older handset.
Fig 39: A magneto model , not used in Australia, was produced
with the old handset as Model N2200C or with a bakelite handset as Model N2200B.
