Maybe, but that's a hard call as there aren't many originals to compare with, and there could easily be variations from producer to producer, or in time frames. I think it looks good, and is a good representative of that pattern of an 18th c. English scalper. I have a pic of a relic blade that has that slow S blade pattern you chose. Almost exactly. The pic I have was identified as a William Parker made. In fact, I have a pic of one in the Troiana collection that has wide flats, if I recall correctly.
