Hi. So I am new to everything silver. My wife's great aunt passed away and left her this pot. It has sat in the cupboard for five years. I am trying to find out exactly what it is? I have searched the internet to no avail other than to find out it is likely a coffee pot. The only clues I have is in the bottom it is inscribed Charles Harrod New Orleans 1832. The internet mentions that his son was a famous engineer in New Orleans but there is no other mention of Charles. There are also three hallmarks placed into the bottom of the pot but I have been unable to ID them after looking through several websites and books from the library- the first is of a bust of a man, the second is H&G, and the third looks like an eagle?
I apologize if I am in the wrong forum as I do not know if this is American or even silver. However, I know that all of the other pieces she gave away to family members are sterling.....here are some pics. Any information you can give me would be a huge help!
