Here are two more examples for the mix. The first is from an English table saw die-stamped "Rosling / Cast Steel" surrounded by three crowns. The second is from an American saw with a partially readable die stamp (which I show). The handle reminds me of those of Wheeler, Madden & Clemson and of some saws made by Cortland Wood, with the top edge gradually sliding down to the hound's tooth. Somewhere I have another saw of the same handle shape and medallion that's etched with the name of a Boston hardware dealer. I think the name is Dowse. I'll keep looking for it.
