I'm watching a powder horn on that infamous auction site that I cannot mention here on which the reduced area from the body to the spout is painted blue. I can't post a link here but would be glad to provide one to anyone who sends me a PM requesting it. The body of the horn is engraved and has a nice patina. It is claimed the horn is circa 1770 and I find it to be quite attractive but the buy it now price is $3500 so I'm watching just for fun. Now to the reason for the post. Just how authentic and common would this be (that's 2 questions)? I really like the look and have a horn that would respond well to the paint. Though I consider myself reasonably familiar with vintage horns this is the first example of a painted horn of this style I have ever seen. I'm just dying to paint my horn like that one and I realize that a lot of folks would rightly challenge me for it, can anyone direct me to a source that would provide documentation for the paint?
