Vintage and hard to find Western Electric model 320.  From what I read this is a MINERS safety phone.  Made of CAST IRON and heavy duty.  Meant to hang on a wall.  It appears that the rear section comes off and you can bolt that onto a wall then reattach the front.  The cord (not for the handset) comes out of the top.

10 1/2" in diameter not including the cradle.

Scuffs and scrapes.  Some loss of paint.  Cord has issues.  UNABLE TO TEST AND PLEASE SEE PICTURES.

GREAT PROJECT!...or use for display.  UNIQUE FOR SURE...and hard to find.

Location G3, MER
