Beautiful Green 10 button touchtone made by Western Electric. This is the 1500 model and its a rare phone because most were 12 button. This is one of the very earliest touchtone phones. They were made for a very short time before the 12 button phones came out. This one has its original green cords and a line cord in green. 

Green is one of the colors that is harder to find in the 1500 model.
