I just purchased what I was told a Oliver 550. When I started buying parts to get the tractor running I noticed they were slightly off. Some Genius had taken what looks like spray paint to the entire tractor and i mean the ENTIRE tractor. Once i found the serial plate i found the following numbers SER# 47-324 518 Spec# 25-0036 the tractor came with a loader. I am new to Oliver spent most of my childhood around old Case and JD tractors. Anything anyone can tell me about this tractor would be helpful. 

Also the reason I was told it was a 550 is the sheet metal in front appears to be a 550. Can you put 550 sheet metal on a Super 55.
