Here's the photos for you Stacey!

The first thing you need to do is stop the progression of the rust.
No weights with it?

Thank you for posting the pics. I have yet to figure out how to do that on this site. Were you able to see all 11 photos?

My only plan at this point is to get the rough rust off/top off with a light mineral oil coat. Not sure about the copper except for good 'ole Brasso! lol

No weights but there is a 7lbs mark in the center of the arrow at the top.

Unless there is some sort of an historic hall mark or history about the piece....it's just another balance scale......and would be really handsome with the rust removed and the brass polished up!

Here is a link that might be useful: all 11 pics

Thank you very much for the information and the encouragement to clean it up. I'll see what I can do and if it turns out ok.. I'll post a follow up! Thank you again for your time and kind assistance. I hope you have a wonderful day!

Best regards-
S
