Ericsson standard auto desk instrument.

Introduced around 1951 and known as the 1000 type.

Available in Black, Ivory, Chinese Red,  Jade Green or Mother of Pearl (Supplied to the Royal Palace, Baghdad).

This is our latest automatic telephone and is alternative to the N1002 type instrument, the efficiency of which has made it so popular. The new set gives equally satisfactory service and includes the same types of components in a redesigned case having rounded contours of aesthetically pleasing shape.

The design of the cradle and the plunger mechanism ensures smooth, reliable operation, whilst the handset and automatic dial, being standard B.P.O. type, are of proved efficiency.  Later models were fitted with the N5875 style handset from about 1955 onwards.

Alternative marking can be provided on the dial label and number plate to suit customers' requirements.

The internal components, comprising induction coil, capacitors, ringer, cradle switch, and screw-terminal blocks for connecting the dial and desk cords, are mounted on a metal base-plate attached to the case by four captive screws. The equipment is thus removable as a unit and is thereby very accessible for maintenance. Perforations in the base plate ensure audibility of the ringing signals.

A diagram of the connections is fixed inside the case.

The line wires are attached to screw terminals in a moulded Bakelite case connected to the telephone by a flexible cord.

All the components are of standard, proved type with finishes suitable for temperate or tropical conditions, as specified on the order.
