Here are photographs of a Revell 1:72 scale PT-109 that I built. The build is pretty much straight out of the box. Besides the paint scheme, the only non-kit modifications are brass wire around .50 cal. gun mounts and behind 20mm; brass wire for .50 cal. gun barrels, a wire antenna and a radome (which may or may not have been on any of the actual MTB Ron-10 boats). The camouflage scheme was done with Floquil base white spray and lots of HO-scale model raiload safety stripe decals. The scheme is far from "exact" as it is my personal generalization of what I feel is a pretty unique WWII paint job.
