DBH 1001, DBH 1002, DBH 1003 and DBH 1051
Introduced in 1932, this Bakelite telephone was designed by Jean Heiberg between 1930 and 1932 for Ericsson in Sweden. From 1947 the telephone was redesigned with softer, more rounded edges and designated the DBH 15.

The telephone was offered in white melamine (DBH 1003), black (DBH 1001) and mahogany (DBH 1002).

These telephones have a built-in polarized ringer with high sensitivity and are suitable, when a strong signal required.  In the case of conversion to Automatic working, the blank plate on the front of the case is replaced by a dial.  The inner parts are assembled on an insert and easily accessible for adjustment.

The DBH 1051 (black only) model includes jack plug, but not a wall bracket with jack, which can be ordered separately.  Suitable similar wall mounts complete with  a jack are:
For surface mounting NEG 1001,
For recessed mounting NEG~2001.

By means of a DYY 1012 shelf, the devices can be mounted on the wall.

Dimensions:
Height 139mm, width 233mm, depth 178mm.

Weight 2.3 kg

This telephone was sold in the UK as the N1020.

This Bakelite phone is officially known as Ericsson DBH 1001, and later as M33, N1020, and ED 702, was a Swedish line of telephones produced for over thirty years between 1931 and 1962.

The Ericsson DBH 1001 of 1931 was a collaborative project between the Elektrisk Bureau in Oslo, Televerket (Sweden) and Lars Magnus Ericsson (1846�1926). It was designed by Norwegian electrical engineer Johan Christian Bjerknes (1889-1983) and Norwegian artist and designer Jean Heiberg (1884�1976). It was the first Bakelite phone with integral cradle, dial and ringer, and was very modern for its time.

Until the early 1930s, the housing of the Swedish phone models was made from pressed steel. Material change from steel to Bakelite brought new opportunities in design, while also reducing the production time for the housing. The Bakelite phone was not only compact but also light at just below 3kg (6.6lb), and could be grasped by one hand. The device with its simple, curved angular design became an instant hit with the industry as well as the consumers, and was highly influential. In most of Europe, it was known as the 'Swedish type of telephone'.

Already in the mid 1930s, Ericsson showed a white Bakelite phone in advertisements, often in the hands of a young woman. However, this model seems never to have been offered to the public. At the 1939 World Fair in New York City, Ericsson showed a transparent variant made of acrylic and Diakon plastic.

The standard colour of the phone was black, but there were also variants in drab brown, red, and green. The process of using Bakelite did not permit the production of bright colours. The device was manufactured from 1933 in a smaller format, and from 1947 redesigned with softer, more rounded edges as the model designated M50. It was also offered in white melamine. The metal dial rotor was replaced with a plastic version, and a spiral cord became standard.

During 1950, Ericsson also experimented with a keypad version, instead of the usual rotary dial, but it would take another ten years before they became standard in Swedish phones. In 1962, the Bakelite Phone was replaced by the Ericsson Dialog model.
