Hey Larry,
     Your older Olivers were a darker green and after the Hart Parr 70 the color changed. Apparently in mid  1952 the color changed again and the laster fleetlines, the supers, 3 didgits and 4 didgits were all the same green. I have paint code #'s if you want them.
The super 77 is the same as a really nice 1850 I got recently. <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: -->  By the way, the 1850 looks good with the snow thrower on it ... still have to put chains on the rear tires, perhaps this weekend. I see there is a block heater on it, did you ever use it? I (have yet to check that out, but I have a new spare on the shelf if it is NG.)
 We got an inch of snow yesterday, our first....not too impressive!
    Are you working on that orchard tractor yet?
