Utah Belt Fs

Does anyone Know what Eric Brooman’s F unit’s looked like?

See Great Model Railroads 1997 page 24. Very similarly equipped to SP F-units painted in DRGW golden yellow with grey roof/window mask, Roman lettering on the sides under the louvers, “UB” under the lower headlight and three horizontal stripes going back from the nose lifting rings and ending in a 45 degree angle cutoff just forward of the cab access ladder.
