I have 2 Grote 7624s. One red, one blue. The blue is a franken beacon. I bought both of them from the same guy at a car swap meet in Louisville, KY 20+ years ago. The blue one has a federal signal lens, federal signal older style motor. It turns extremely slow because of this. The red one is all grate, in great shape, no cracks/crazes, anything like that. I can take pics/video of them if you're interested in either.
