A steelyard scale ... with a wooden beam

[fernando]

Maybe not so common to see in the West, where beams are usually made of iron. The little brass brads along the wooden beam have no section digits to help reading; you need some experience to figure out the weight.
The structure in which both suspension hooks hang is rather peculiar ... to me, for one. 19th century, i would say; not newer than that, for sure. The seller bought it in a street fair in Silleda, Spain (Galicia).
Total length 51 centimeters.
Have you guys seen similar examples ?
