Bell System Western Electric Black Push Button Multi-Line Phone Office Telephone

Shoulder Rest in Black Color on the part you talk and hear on.  It is attached by two sided sticky tape, so it can be removed if desired.

Has 1 red and 5 clear push buttons along the bottom edge of the phone.

Wall connector is a computer type cord, almost looks like a old printer cable connection.

Has dirt and minor surface wear.

Seems to be from the 70's.

Sticker on the bottom has 2565 HKM, probably the Model number.

Does not have any cracks.

I do not have a way for this to be tested that I am aware of because of the funky wall cord.
