Some signs of wear

Square in solid brass signed Lenoir
Having been the manufacturer of the comparator on which Borda and Lavoisier made all the experiences concerning the platinum and copper rules, used in the setting up of the metric system,
Étienne Lenoir has been appointed thereafter to produce the provisional meter, and then the final meter and a series of standards to be provided to the 83 departments created in 1792, this work started in November 1793 until 1800.
Length of the square 176 mm and width 21 mm
