I too would lean towaard a slightly later date, for a different reason.
"Country-of-origin" marking was clearly not a legal requirement in the
nineteenth century. The earliest trace I can find (in Wikipedia) for American
law is in the Smoot-Hawley Tarriff Act of 1930. That is close enough to my
impression, which was that country-of-origin marks first appear around the
1920s. In the 1930s, I doubt Buck was importing chisels; struggling not to lay
off skilled staff is more likely. After WWII seems a reasonable guess to me.
