Below is a Dean Heacock pic of the
real #3301. It was sold in 1985 to the Seaboard System and was scrapped
shortly after.
My U30C is actually a U28C model that I have modified to be a U30C. I added lots of details and Herald King decals. Mine is also a "dummy" that means it doesn't have a motor in it and won't move on its own. I make all of my "dummies" have odd road numbers, and powered units have even numbers. This eliviates any question as to which run and which don't.
Here is a starting pic.
Below are my finished pics.
