Was this the original color? Just curious. The serial number on the case is NK1108 so I believe it matches the year of the truck. Thanks in advance. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | Yes, that is the correct color. The 3rd members for the Passenger cars were painted a similar manner, but with a more brownish-red shade.

Is that the first year for orange? Is that why the differential/housing is often called the "Pumpkin"? Here is a confirmation of the NK code. | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | Orange?
Is that why the differential/housing is often called the "Pumpkin"? I like that question Tim. I never thought about it, but that makes sense. I think I know the answer to the question I asked Bill above, but I wanted him to be clear with his answer. I believe only the center section/pumpkin were burnt orange.

Thanks, 55mater, Bill, and Dave  I learned something and I now have an new BS story/hypotheses regarding "pumpkin". | | | | | Joined: Apr 2015 Posts: 37 'Bolter | | 'Bolter Joined: Apr 2015 Posts: 37 | Thanks for the info. Now I just need to figure out how to match the color. | | |
