A little while ago I took it upon myself to start tracking down as many of the (currently) known past-and-present locations of cold-war era H.O.R (Harry O. Ricci) model "Super Sirex" sirens.
Obviously, I haven't tracked down every single Super Sirex location, but with the help of a couple of other fellow enthusiasts, I have uncovered a lot of locations over the past several months, a great majority of which I did not have prior knowledge about.
That being said, here’s the link to the map: https://www.google.com/maps/d/viewer?mi ... 000002&z=8
If anyone has any questions, comments, or recommendations, feel free to let me know!
