Three zeros are positioned in radial symmetry on one side. The other has four lines of writing, two straight across the middle and one curved above and below. Possibly BACK????? / FIAI / OZMA / S???

From Paul Cannon, "This seems to be a Hungarian flour seal with inscriptions in Hungarian. My suggestions are that this can be read and reconstructed as:
BACK [BERNÁT] = Bernard Back
FIAI = sons
[G]ŐZMA[LOM] = steam mill
[SZEGED] = Szeged (city in southern Hungary)

There is a complimentary seal to this on Bagseals Bernhard Back Söhne, Flour Bag Seal, Image & Found by Lancastrian where all the inscriptions are in German. In the Hungarian language the family/surname is written first hence the different name order in both seals. The company of Bernard Back & Sons were a major player in the Hungarian mill industry Back Bernát, from Wikipedia."
