Bell System Western Electric Green Push ButtonMulti-Line Phone Office Telephone

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

A small black box on the side of the phone with a white push button.  It is wired inside 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.
