My sis watches the Hercule Poirot movies shown on A&E, and PBS.  She
says she would love a phone like his for Christmas.  I assume it is an
Art Deco phone, but I need to know specifically which phone it is.

There are several different styles of telephone in the "Poirot"
series; the time period of the Poirot stories spans several decades.

The Hercule Poirot stories were written between 1920 (The Mysterious
Affair at Styles) and 1975 (Curtain) although the 1930s is usually
regarded as "The Golden Era" of British crime fiction.

A British phone in a home of the 1930s would most likely be a 200
series, such as items 4201, 4202 or 4203 at

This Siemens Neophone style was introduced in 1929 and the 232
version, which had improved circuitry, in 1936. This telephone became
the GPO's standard table set and were in use up to the 1960s or even
later.

Whether this is the type of phone used in modern movies is another
matter, of course.
