American Optical / AO Lensometer Model M603B Made in USA - Vintage

Description

This will make a great decoration for any Optometrist office, home office or as just a shelf conversation piece in your home or business.
I'm not selling this as a working piece, as I'm sure there are many more modern ways to test eyesight,  and I also have no clue as to how it works.
It is in Very Good Pre-owned Condition.  There is only a small amount of paint peeling on one side.
It is HEAVY! this will affect shipping.
Please see photos for detailed condition assessment and Feel free to message me with any questions you may have before purchasing.
Thanks for looking!
