Hi,
I agree with gth.
I have seen loads of these type weights at the Naschmark in Vienna.
They all are confirmed by the stall holders to be 100 years old plus

with 100euro plus price tags!!
Ocasionally you find a genuine one in amongst them, I have an engraved and dated one from 1908. I consulted with a master engraver here and he confirmed the age.
Kind regards
