This is a Picture phone made by Western Electric. It is the Mod II model. Bell Systems Picture phone Mod 1 was displayed at the 1964 Words Fair. Later on, the Mod II came out.
These are very rare. I don't think I've seen another one in Moss Green. There is a lot of Information on the Western Electric Picture phone if you search thru Google. A lot of history on this interesting, rare phone. There are videos and online pamphlets. I don't think you will be bored reading about the Picture phone.
Embossed directly under the Screen Bell and Western Electric Marked Bell systems in several places on the underside of the mail hosing and stand.
Embossed Western Electric in the metal on the underside of the controller and stamped 6/70 in crimson ink.
