I have what I am sure is probably a replica(?) Of Trigger, Willie Nelson's guitar.   It was autographed by not only the Highway men but other singers as a gift to Wllie.   a good friend of Willie's and songwriter Buck Jones toured with him and I have pictures of Buck and Willie together plus negatives.    Willie Nelson, gave the guitar to Buck along with a pair of his boots, bandana, guitar picks, hat and wall art. It seems authentic, just don't know where to even start authenticating it.   The names I can distinguish are Johnny Cash, Kris Kristofferson, Jennings, Roger Miller, Rita Coolidge, H. Leopold and others... here are a few pics...
