A fully complete set of drawing/mathematical instruments in brass preserved in its original leather case lined in red velvet.

Lang, Mechanicien du Roy pour l’artillerie” (see websterdatabase and Marcelin). Lang is active between late 1740s’ and early 1760s’.

Furthermore, Marcelin cites a drawing set in private hands which is certainly the present set in perfect original condition.
