Sam Colt Custom Edition

[Possum Toed Rick]

Howdy All,
I need a little help with the value of a Colt Revover, This was offered to me last week but I have no Idea what it's worth. According to the Colt Custom Gunshop there were only 500 made. It is in pristine condition. It's probably the only one in Austria and I havn't the foggiest as to it's value. I would love to add it to my collection. I would be grateful for any help.
Thanks,
Rick
