Ericsson AB702
Ericsson's wall set made from oak. Stained to very dark.
This model with bakelite handset introduced 1932.

Phone has no serial number.

It has several times stamped "VR" which means "Valtion Rautatiet" (State railway) here in Finland.

On the back of the phone is text "Oripohja" which has been a flag stop between Orivesi and Haapamäki.
I belive phone has been in use there.
