The whole network has not been changed at the same time. For this reason, we can find some strange phones which were originaly designed to work as local battery modified for a common battery AND automatic network. This Marty1941 equiped with a dialier is a good example.
The PTT24 series
PTT24 mobile.
In 1922, French administration ask to manufacturers to design a unique type of phones. The PTT 24 is choosen in 1924 from where come its name. It was since the beginning foresee for the automatic network but it exists in local battery version. It's electrical characteritics are very goog (microphone is very sensitive and it's very robust).

It has been also designed for wall mounting, but the shape is far less attractive.

The U43 series
U43 mobile.
The phones which have been the first designed to be used by everybody is the U43.
It was made to comply with the following statements :
To be universal, means one can connect it on either common or local battery, automatic or manual switchbard networks
The cost should be less than previous ones like PTT24
The war restriction caused lack of steel : all its components should use other materials
Because of that last requirements, it is made of Bakelite, which can be easely molded.

It has been designed by Société
des Téléphones Ericsson, the french branch of Ericsson located near Paris. Its shape is based
on the Ericsson 's 1931 model.
It is named U43, where U means Universal, and 43 its birthdate.
