Here are the pictures on that Oliver “Tug” or what might be a Airport Tug Tractor.  This gas standard type tractor was used at one time by a circus out there in CA I was told for many years.  It is near Reno, NV at present and the engine is stuck.  Model 80 and Serial # 900467C41 which is listed as a Industrial Model 80 (1945).  The price on it as-is is $1300 there.  

I told Oliver Magazine about it and they wanted some pictures which I emailed them too now and they might include it in their upcoming Industrial issue in January.  I wrote them after hearing they were coming out with a issue on the Industrials line.  We know Oliver made the very rare Airport 25 (from the 70) but can’t find too much info about a Tug 80 tractor or if they ever designated such a thing which is why I started this post as you recall.  This article should be helpful too since I believe the factory did do some customs and send out models with various options.  Again this has 22” brake drums which apparently were that large for when they unloaded large object off the circus trains and that.  Looks like it started out yellow from everything we can tell, and then blue and orange circus colors later.  

Hopefully the 2 pictures show below but if you can't see them email me at <!-- e --><a href="mailto:CashMoline@hotmail.com">CashMoline@hotmail.com</a><!-- e --> or look here at this page I tried to put them on too- <!-- m --><a class="postlink" href="http://greenacresequipment.com/Oliver80.htm">http://greenacresequipment.com/Oliver80.htm</a><!-- m -->
