While looking for something else entirely, I ran across several photos on the website of the Boston Museum of Fine Arts of armorial silver belonging to Benjamin Faneuil (1701-85), brother of the Boston merchant and philanthropist Peter Faneuil for whom Faneuil Hall is named.

Up to now, the only surviving evidence I’d seen was on Peter’s tomb at the Granary Burying Ground, which has no indication of tinctures.  These engravings make clear that the charges are red on a silver ground, with the exception of the annulet surrounding the cross (too narrow on either piece to be hatched for tincture, but probably Gules as well.

So I’ve updated the REAA listing accordingly.
