If you have the engine serial number, you can call the Floyd County Museum at 641-228-1099 and they might be able to find the build card for that tractor. If they do, it will have the tractor serial number on the card. There 505 Super 77 Industrial tractors built, of all fuel types. At least 81 of those were for the military. The information to figure out how many were diesel or gas is contained in the build cards. But they still have to be transferred into some kind of database, a daunting task at best.

The industrial used the same sheet metal as the Ag tractors, but the paint and decals were different. Check out <!-- w --><a class="postlink" href="http://www.oliverdecals.com">www.oliverdecals.com</a><!-- w --> for decals.
