This bow was stamped by Béla Szepessy from around 1880. I know only two bows stamped by him, they are definitely the works of the same master. They show the marks of the German school, they are ripe, mature and tasteful stylish works of art representing the best quality of bow making of the age.
It was common practice that violin making masters bought bows and later stamped them with their own stamp just like Pál Pilát did. However, we can see from the quality of the Szepessy bows that they were of the same standard as the works of German masters of the period, nonetheless they do not resemble any of them. Szepessy had the chance to study bow making while working as an apprentice in the Nemessányi workshop for three years together with Carl Hermann Voight. Voight was an accomplished bow maker who came to the Nemessányi workshop to learn violin making. I cannot prove undoubtedly that Szepessy made the bows with his stamp on them, but I would say that these bows are his works.
