Nope not a rip off, it was all original, donated by the family of the original owner I think to the car club, then they restored it, and gave it to the Historical society and it spends its days drained of fluid out in Bismarck.
And I don't know what years Olds had it other than 1916, but then again I never even knew Olds had a flathead V8, let alone a V8 in 1916.
