A few years ago I would have said that a low serial number didn't mean much to an Oliver collector. I don't know why this is so, because people go wild on serial numbers for the other brands.

I think that is starting to change. With the build cards now available for most of the Oliver tractors, people are getting more into the specific history of their tractor, and I think this has created a new interest in serial numbers.

If something has happened to the first 19 Super 55s built, that would give you the oldest one. If numbers 1 through 19 are still out there, then 20 doesn't probably have a special value any more.

Overall, I would not part it out if it were mine, because it may be the oldest surviving one. If I knew where there were a few with lower numbers, I would then be more tempted to part it out. My opinion, for what its worth...
