http://www.corbin-russwin.com/ - eliminates one clue as to the key's origin. Unfortunately, finding the right lock would be a whole lot easier if Corbin was the name of a building.
I won't sit on this one for long, I want to get it back out there, but I also want it to travel at least a little bit.
Thanks, Bad-company.
Interestingly enough, the key at this site looks just like it, except all dressed up. (Scroll down to rhinestone skeleton key brooch)
