It's interesting to me that from 1932 until sometime in the '50s, Ford used the symbol "V8" as if it were their exclusive property, and nobody except Cadillac seemed to challenge them. They used many different graphic expressions of the V8, but they only used it on Fords -- Mercurys were always badged "Mercury 8" or "Mercury Eight". These examples don't represent every variation; there were others that I haven't photographed, but this shows a lot of them. These are in roughly chronological order: '33 ('32-'34 are very similar): '35: also '35: '36: '38 Dlx, I think: '38: '38 again: '40 Std: '40 Dlx (Std was the same except for paint color): '51-'53: '54-'55: ...and here's one of the rare exceptions to the rule from this era, a '30s Cadillac: Fiat built a small V8 engine in the early '50s, but there is a belief that they thought Ford really had some exclusive right to the mark, so they called their model an "Otto Vu" or 8V instead. I don't believe that Ford really had any exclusive right to the "V8" designation, but it's interesting that apparently nobody challenged them on it. Even GM, when they were introducing important new OHV engines in the '49-55 years, never used more than a V (sometimes with a brand logo attached) to signify the presence of a V8 engine. This isn't important at all, of course. I just find it kind of interesting.
