Good eye Tom! Yes, Gary over at Decal-It did make them he also made a set of decals for a Civil Air Patrol livery for my Cessna 182. I am also planning to order some N number sets for the Ryan SC-W & SC-M project. I like his work! The decals are 1/5th scale and I laid the dime in the middle to give a sense of scale. The Ryan S/N plates were made with three different engines listed.
