I wonder if the decals were just trimmed to fit the mis-oriented fins. My bigger issue is the description of “very good” condition. It’s in poor condition. It needs a LOT of work, which would include decal replacement. I would just build a clone. You can get many of the parts from eRockets, including a set of decals. The decals are so simple I would just use cut vinyl.
