A number of makers sold refrigerator car kits in American OO, many of them being not too visually successful.
As noted in the previous article, Trout was a Disney illustrator. At first I was thinking maybe the sides were silk screened, they are not commercial sides and were not lettered with decals, but with a closer look I believe that they were entirely hand decorated. The logos, the small lettering, everything! He had the hand and skills to do it, and the result is eye popping. They look wonderful in a train on the layout.
Back to the topic of reefers built from kits, S-C reefers are a bit tall as are Nason. The latter (depending on the body – they vary) is closest to accurate for OO, as the early PRR boxcar body they based their bodies on is not 15’ tall. In any case, the down side here of the arrival of these Trout reefers is most of the other reefers I have now don’t look “good enough” on the layout. For once I am thankful that the layout is small!
