I need any information concerning a Stephenson Model DM4 siren. In particular, a schematics or a copy of one would be much appreciated.
That was my thinking, although they did have some products that I never saw a "bigger name" attached to. Their lightbars and a few sirens are examples, but I would agree they probably weren't actually making them themselves. I don't doubt that someone else made a lot of their stuff, I just don't see who that is in the cases of a few products. Lik in this specific case S&W seems to be the largest company to use this design. The design was obviously rebranded as cats eye which is the smaller company. In the case of Whelen we know some of their sirens were made by SVP/Carson or whoever was making their sirens. I would be curious to see who actually made S&W stuff, even if it was an electronics company vs. an existing warning company. IMHO in this case the answer is that this is at the lowest (or highest) level a S&W siren, even though they didn't really build their own stuff.I think it is unlikely that S&W actually made them. S&W products other than firearms were made by other manufacturers and labeled as "Smith & Wesson".
I was hoping you would chime in. I think the bottom level of reseller here is s&w brand-wise... They would have been the main brand that sold sirens that looked like this.I have the Smith & Wesson Magnum IV. It is exactly the same. The Magnum series sirens from that production period (c. 1972-1975?) sound like the Federal Director and Interceptor sirens of the late 1960s (with deep slow rising wail and yelp tones).
I also have a Magnum IVB. It's a later version (likely early 1980s) with small pushbuttons. It sounds closer to a Carson/Whelen/Southern VP siren from the early 1980s.
Someone told me that Carson made sirens for Smith & Wesson, but I don't know if they made the entire Magnum series or just the earlier or later versions.
