The biggest portion of my collection consists of sales literature, old photos and other memorabilia.  The literature comes in very handy when looking for material for the magazine.   I have quite a few Oliver toys and several walking plows.  I also have a nice horse-drawn manure spreader.  My tractor collection consists of the 77 RC, gas that I use to farm my 10 acres with.  I also have a 66 vegetable special with a single front wheel that I got from California.  It&#039;s patiently awaiting a little TLC, but eventually that will be my show tractor.   I use all Oliver equipment on the farm, but it&#039;s part of Dad&#039;s &amp;quot;you store it, you can use it&amp;quot; loan program.   It&#039;s just an opinion, but I think Oliver had the best looking tractor out there.
