Keith,
Nope, it didn't come from Colorado... and your memory is a little foggy... horns from out there aren't really that cheap! This one came from a picker in New York. When I checked the other items she had listed on Ebay, it was obvious she was into modern household items and decorative items, with no interest in pieces related to firearms or early history. I felt badly about jumping on the horn since she had no clue about what she had, other than it was dark and dirty and she was probably glad to see it go. But if I hadn't grabbed it, someone else would have in the next minute or two.
