I think the double pressed tabs were designed to hold a flat sheet of plastic as a divider instead of the full plastic trays like Bally and Williams used. Thanks for posting the actual dimensions. It will probably help someone (like me) when searching for the correct one in the future.

I have never seen a SS cash box to my recollection. At least, I never paid that close attention back in the day. And, just about anything I have today is either powdered with white corrosion or that beautiful orange rust.
