Does it have any sign makers markings? I've been asking everyone I know and every Harley collector I know trying to sell this thing for you and they all say Harley never used the word "distributor" on a sign. And that its more than likely an 80s-90s made sign.
I showed this to my Dad, which I consider him a Expert in the Antique motorcycle field as he has owned tons of Harley and Indian Memorabilia along with tons of Motorcycles and is still very active in the Hobby. He said the same thing about the word "Distributor" he said it should say Dealer, he said he would steer clear of it.
