Werden manufatures WWII air raid sirens following the same design that the original sirens did, making this a very cool company. The sirens are specially ordered, following 3 different options of sirens, the P-127, the B-115 and the C-125. Overall, this company is very old school, making good sirens like they used to be made.
Awesome company, and friendly employees. Professional services and great Sirens.
