My father bought a used 18-28 cockshutt Hart Parr on steel approximately 1940.  About 1945 he had it converted to rubber tires.
I spent many hours on it working our farm here in Manitoba Canada in my growing up years.
It was an early 30s model, &amp; came with [b:s6ooaaak]Cockshutt [/b:s6ooaaak]decals on the fuel tank, &amp; the raised lettering [b:s6ooaaak]Hart Parr [/b:s6ooaaak]on the front of the radiator. Nowhere was the name [b:s6ooaaak]Oliver [/b:s6ooaaak]that I can recall. Has anyone else heard of this discrepency in the name on the 18-28?
I have looked at my museums &amp; tractor shows up here in Canada, &amp; have not found an 18-28 model.
 I have been able to download several pictures of working model 18-28s from internet sites &amp; they sure bring back memeories.
