Pelouze Laboratory Scale

This Antique Vintage Scale was probably used by some famous Scientist, or maybe not?
It uses a metric system (Probably inspired by the French), includes a few brass counter weights, some surface rust,
missing paint and more! - Does Include a somewhat tattered original box, tested to the best of my ability,
but not sure if it is actually working?

This would make a lovely gift for someone recreating a Vintage Laboratory or just a 
collector in general.

View the picture and decide for yourself.
