Ken,
There's a very faint etch, or portions of an etch, most visible where the darker patina lays. So faint that I can't make out any of the letters, although the font does appear to be quite thick. The one in the catalog picture appears to have the Ellenville stamp, which was a quite early stamp, and was closely followed by the "Ulster Knife Co. NY" stamp that appears on the one above. I wonder if the etch remained the same over the years.
