Is anyone familiar with the "Thos Cahill Boston" backmark. Dug an eagle button with this mark. I believe there may be an "A" in the center but cannot be sure as the center of the button is dented and corroded and the shield is not discernable at all. Does appear to be part of a faint "A"" in the center but I could be imagining it.
Cannot find the backmark listed in Alberts book.
