I'm new to this so apologies if this is basic stuff. But we have a family heirloom silver teapot, very intricate and engraved in honour of a wedding in 1852. The picture of the hallmarks is shown below. I'm wondering if anyone can help fill the gaps here or correct my understanding?
* E&Co matches Elkington & Co of Birmingham
* The worn mark on the right is presumably the Sterling mark, although I am a bit surprised it and only it is worn.
* I don't see any city mark? Unless the mark on the right is actually the Exeter symbol, but why would a Birmingham manufacturer's output be assayed in Exeter.
* There are two year marks, M and is it E? Or C? Or G? Looking at pictures, E seems most likely to me, but expert eyes appreciated! If this was London, that would be 1840 and 1847, which puts it in the right ballpark if it was acquired and engraved only later. But why two years?
* What's the N in the diamond at the bottom?
* Is the 2392 anything to do with hallmarking?
Many thanks!
