It's most probably a Romanian cast steel imitation of an Austrian style anvil, minus the cathedral windows. (It's surely cast . .judging from the shape of the horn and the line down the middle)
Romanian made anvils made during the communist period bore no markings. .if they were made for internal use. They were also more functional than aesthetic so only the face was machined. the rest of the body being left as cast. ( exactly like my German double horn - only difference being that that was cast at Topletz)
If you found it near you it's probably a "limited edition" model cast in Resita.
If so. .keep it well .. Resita was making very good steels back the in the communist period ..although they lost many of their formulas after the revolution.
