Canadian CLM Siren Sirens Main Back to Civil Defense Museum Main		I don't know much about these Canadian CLM sirens other what can be seen in these photos. I do know they have a 10 and 12 port rotor and sound similar to a Federal 2T22 but "raspier." These photos were on an Ebay auction page years ago when someone tried to sell these sirens. They are posted here for interest. If the photographer sees this page please let me know and I will credit you for the photos or if you want these photos removed from this site please e-mail me and I will remove them. I have no idea whatever happened to these things. I don't think the auction received any bids and they weren't relisted again that I know of. There are several videos on youtube of this type of CLM siren. I think the best I have seen is this video here. http://www.youtube.com/watch?v=8JmzWPHokfM Click the photos to see larger.
