Kinda looks like a piece of 'stock' finding , such as 'crafters' might use for a small project (if silver , this piece would have been bent around a mandrel , usually with a rawhide hammer).
I'd give a guess that the soldered joint is made from a thin brazing rod , perhaps with a small amount of silver in it .
Still guessing , but would be nice to know what metal was used for the band .
I'd also guess that it's not antique (100+yrs old) .....but given 60 or so years ....
