My mistake . Cadman was manufacturing up to 1965 & altho the first laser was made in 1960, I still doubt there were any laser etching machines made so soon & even if there were, why would a company...

I doubt they had lasers between 1700's & 1906 :)

I didn't think there was any patent on etches as evidenced by so many makers using the "eagle" logo but have only seen that one on Butlers.
