These photos are of the
actual prototype designs considered for the final look
I've lost the information on the identity of the photographer of these pictures.
This is the early Siemens
prototype phone that was used as a model for the Erifon (later named Ericofon).
This one looks like a car
to me.
Not much difference from
the previous picture. Too bad I don't have any pictures of the dial faces.
Very similar to the first,
but the base seems a bit different.
This blue phone was the
final prototype taken to management for approval. You can see by the paint it's been
around a while.
This is a prototype of the
Model 700
Another prototype of the
Model 700. This version retained the thumb groove on the neck.
Besides the thumb groove and the position of the sound holes, this one
looks a lot like the final version.
