Sorry, Sapphire! I was getting ready to go to work and wasn't reading carefully enough. I will have to post the pictures of the powder horn later. I can say though, that the top is intact and looks very similar to the top of this powder horn. It is metal, and according to what I have been able to find, THINK it might be copper. That seems to be the preferred metal of powder horns.
There are no suspension loops. There is one small hole up near the top where it looks like a loop may have gone. Attached to the horn, is a small loop and pin that has a split bottom as though one would insert the pin into the powder horn and splay the pin to secure it to the horn. I am not going to even try that, as I am afraid the pin might break. I am sure it is more valuable just as it is without me monkeying around with it!
I will post more picts of the horn this evening.
