Help Identifying Maker's Mark

[mgolab]

Thanks very much Jim for the comments. I have a copy of Sword and Blades of the American Revolution and agree that 34.A is very similar in respects.

I have included another image of the heart, with the "S".

I suspect 18th century, but whether English or American is a mystery.

I am also wondering whether Highland. I also read your prior post about hearts and Scottish broadswords. I know that the 42nd Regiment implemented a heart motif on their belts in the American Revolution. I also read that the 42nd carried belt axes later on in the AR.

Thanks again. I appreciate your feedback
