In 1972 I bought what I thought was an Oliver 80 standard. Used it on the farm for a few years and parked it. A few years ago I got it running again and it was then that I noticed the plate on the engine said that it is an 18-28. It had 80 decals on the fuel tank and they looked original. Started asking questions and an old guy told me that some of the last 18-28s were decaled as 80s. This is a 1937 model. Last year for 18-28s. Here's the stupid question, is it possible it was decaled as an 80 or (this is what I think even though it looked original when I bought it)did someone just put the 80 decals on it later? Got it painted and want to finish it right. Thanks
