The CS Whistler is the oldest siren in the CTS lineup, coming out at around 1924. The siren itself is very robust. It's quite simple with a 3 legged Darley type design. The siren itself is quite cheap coming in at around 100 bucks back then. It was a widespread siren spanning across 15 states mainly used in fire stations. The CS Whistler was one of the more popular choices, managing to sell 400 units. The siren was relatively easy to construct, As the casting for the legs were the same across all of them. the stator is short due to the limited motor power back then, The chopper is a Carter style chopper. With curved vanes the siren was able to reach up to 110 decibels at 100 feet. Quite impressive back then. As the model 2 was the go to siren.

CS Dual-Whistler
The CS Dual-Whistler was produced later in the 1930s. As the 2 rotors were too heavy for the 5 HP motor to spin properly. The siren itself is literally 2 whistlers mounted ontop of eachother. One being 10 port and 1 being 12 port. This siren had a little less range but traded for a more noticeable tone.
