Nested cup weights - polished bronze - Nuremberg, 19th century

Closing weight, beaker weight / nesting weights, 8-piece and heavy 36 ounces, bronze, Nuremberg, smooth outer surface.
Marked on the top side of the lid: jar or goblet, not identifiable, 19th century, Nuremberg.
In the bottom of the tub the number 16 (lead) and the letter L that also appears on the two largest bowls.
In the first, second, third and fourth bowl the weight markings: 8, 4, 2 and 1 (lead).
The largest and second bowl also bear a mark in the shape of a shield containing a T.
The two smallest bowls and the closure piece are, in my opinion, not original.
The closing weight weighs about 400 grams.
Dimensions: diameter of the tub’s top 5.2 cm, bottom 3 cm.
Height of the tub 4.1 cm.
