Fun lot of adjustable rings show some oxidization/patina from age
Some of them look like they have a two tone brass color 
The display tray is included--the foam used to have a velveteen
top on it.but most of it has worn away
The sign in the middle has come unglued and the tray shows wear
please see pics
These would benefit from a good polishing
There are 21 rings on the tray

There is a measuring tape in the pics for
size reference
questions? please ask before purchasing
Thanks for looking!
