Hello all, I just received this Signal Stat model 340 A1, or a rebadged Federal Signal Fire Ball. This version is an older model that still retained the locked base for the bulb. This light came to me with an original dark ruby red lens without the F7 molded into the top. It has been used but not abused as the pictures show. Just a quick clean and polish, no plans to do anything else to it in order to preserve the patina on the metal surfaces, see the pics.
