Well done, the injection molded K-Line PVC is really tough stuff to cut and fit.
Looks great and you'll have a unique model to boot!
Thanks atlpete. This kitbash involved adding a piece of styrene to each large door. That was a first for me. But the real challenge was removing the high rivet ridge line. ABS is tough to remove and sand to an acceptable smooth paintable surface. But the paint looks dark enough to hide some of my mistakes. I am also working on another bash to modify a K-line RPO/baggage to resemble a PRR BM70. (Filling in windows and part of a door opening without the seems show through primer is nearly impossible.)
