Then Google is your friend. I don't have a photo or a link but I can tell you what would have been there. As you look at the end of the car, the brake wheel would be on the left. To teh right of it would be: PFE 47179 (your car number)
On the second bulge up from the bottom you might see in white, centered:
IW WROUGHT STEEL WHEELS
If that decal isn't in your set, no biggie, I have photos of the cars both ways.
The Microscale sets typically come with lettering diagrams that are a big help.
Some of us cranky old rivet countin' chops bustin cantankerous prototype modelers have pretty extensive libraries covering what we are interested in. I am interested in LA where the citrus packing industry was big and the SP and Santa Fe worked across the street from each other quite a bit, so I have loads of PFE cars and more than a few reefers from the SFRD.
