identifying hallmark of 3 angels

I have purchased a communion from 1813, and on the back, it has 3 angels, each holding swords in right hand, and each in it’s own oval with bottoms touching. it makes a trio of identical marks. there are some other marks but can’t make them out yet. I do not have it yet, purchased it online. Thank you for any help with identification.

most likely pewter.
