Interesting post there Squire Drew. Can it be said that "Armour" & "Royal Steel" are American trade names for specific steel composition or are they just marketing names? I'd say that if the "SB&Co" is followed by a letter then it was sourced State side. Can we also guess that Sanderson & Buckley used the same trademark? Just as I thought, "we don't know nothing", to use a double negative for emphasis.

Kind Regards,
