When I was first on the H.A.M.B., I saw a link to "Belmont's" site. At that time, they had the entire Offenhauser catalog on it. Turned out that it was just for reference only, but it drove me crazy for a while, because just about any Internet search for old speed equipment ended up there. They had none of the old stuff.
I haven't been led that far astray since a certain stripper back in '92.
