Ericsson AB120
Ericsson's wall set, called "miniature", has only two magnets in generator and is very small compared to handset, even speaking transformer
has hole in the backboard. Model is AB120, serial number 778771 from 1909.

Phone was missing only crown, did get original one my friend, otherwise in original condition. The lacquer has crackled nicely on the plate were the decal is.
