Does anyone know what the difference is between a model 77 and 78 siren. I have a 78B with a propell-o-ray light on the front. I was also wondering what the "B" was all about. Any info would be great.

The 70 series sirens were designated by their level of finish. The model 76 was an underhood mount siren with no rear housing, and a painted grill. The 77 siren had a chrome housing and grill. The 78 series was a dual tone siren with either a Sola Ray or a Propello Ray light. The B designation denotes a siren with a brake, A is without brake.
