Picked up these teaspoons the other day and it was a maker I hadn't seen before, and hadn't been seen here (from what I could find!), so I thought I would post his mark. Hugh Breckenridge (with various other spellings) only sent items in for assay from 1805 til 1811. He ramped up production a bit as he went on, but wasn't producing a lot. His maker's mark never seems particularly well struck, but you can make it out from the three pictured.
