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...
Hopefully others will chime in. My opinion is this looks to be genuine.
Thank you, yes I would love as much insight as I can get.
