The March/April issue of the Hart-Parr Oliver Colllector is featuring the Oliver 500 and 600 tractors. I think we were able to come up with quite a bit of information on these rare tractors. The issue goes in the mail on the 1st of March. If you aren't a member, you will be able to find this issue on the newsstands at Tractor Supply Company (TSC) stores across the USA.

In the meantime, you can learn some more about the 500 at the David Brown Tractor Club website at <!-- m --><a class="postlink" href="http://www.davidbrowntractorclub.com">http://www.davidbrowntractorclub.com</a><!-- m -->
David Brown of England made these tractors for Oliver.
