The 38AT and the 138AT were the standard PMG automatic (dial) telephone introduced with the new automatic exchanges installed from 1922. This type was superseded by the introduction of the 162AT in the 1930's but many still remained in service until the late 1940's.
The 38AT had a solid back transmitter, while the 138AT was fitted with a No. 13 insert transmitter in a Bakelite housing.
