I was not able to find another 'exact' match to your opener, but there was one that was very close. I don't think we're allowed to post links here in the comments, but I'll message the link to you. I think the metal yours is made of is Bronze. You probably would have gotten a better response, and higher bids if you'd listed this as an 'Antique Bottle Opener'. There are a lot of collectors out there :-)
