is an old Pay Toilet Lock. It is made by the Nik-O Lok Company, Indianapolis, Indiana. It measures 8 1/2" tall, 4" wide and 2" deep and works when I put a dime in it. I do not have the keys for the upper left keyhole or for the cashbox. The finish is in good shape, t are some scratches and blemishes to the chrome but nothing bad. I do not have the mounting screws but I am sure they can be found at any hardware store. Check the photos and email any questions, Thank you.
