So I got my Model 66 Rota-Beam (amber) over a year ago. The base had been painted in a gross textured flesh-colored paint by a previous owner. I finally took it apart and hit it with a wire wheel. Under that disgusting paint were the letters "SHC" stamped into the metal. My initial thought was that "C" stands for "County" and, whatever county "SH" stands for, they love stamping ownership on stuff. Then I thought that this may not be the case, as that little beacon probably wouldn't have cost enough to warrant the trouble. Did these have any stampings, not on the tag, with about ½" letters to symbolize something from the factory? It could still have been stamped on by a company or agency. (County is just my best guess.) I mean, I could picture some shop employee with a new stamping machine using it on everything in sight with a smile on his face. I guess curiosity has just gotten the best of me.
