Description

The old label is stating a "ferritungstit" with the formula, but I can't find it on Mindat.

However the material is reddish (due to the iron I presume) and microscopic. I can't give a guarantee for the labeling and the amount is too small to analyse.

But if you like a nice sample of zinnwaldite from the type locality you can make a good deal on this anyway, with old label (1954).
