These are the Intermountain 40-23 PFE reefers that I got when they first came out, around ten years ago.
The running boards are the one thing that really stands out as not looking as sharp as the models, though there are other errors, I believe if memory serves me right, they look good to me,
So I replaced the running boards with Plano etches that were made for this model, which are quite sweet, and as you can see are really sharp looking.
Finally, here are the cars with the running boards painted, new couplers and with replacement NWSL Code-88 wheels and the running boards painted.
Still got to weather these. Enjoy.
