Antique C 1860 Sheffield George Wostenholm Sons "American Razor" N R | eBay

The etch doesn't look right to me. Part of the A is on the bevel and the etch doesn't look deep enough for that to happen also Unum the U is cut off by the banner and then the weird swirly things too and bottom, I haven't seen those before. Maybe totally off base so I thought I would ask for opinions.
