We are a former tunneling company and I fould this old phone on a shelf. Our company must have used this phone back in the day. The phone is a Kellogg S. & S. Co. phone. The name is shown in raised casted iron letters on the front of the cast iron lid opening. The following numbers ( 2490 ) are shown in raised casted iron numbers on the back side of the cast iron body. I would appreciate any information regarding this phone, for example, ( year it was made, main application for use .. etc .. ). This phone weighs 80 pounds and the cast iron body has the following dimensions ( 9" wide X 16" tall X 10" deep ). Please email me (Andrew) at conequipco@aol.com with any information. Thank You!
