A interpertation/recreation of the federal signal 500/550 DHTT (Dual horn Two Tone) Air raid siren. This was requested by @asc.t135 and includes a federal signal 500 of 550 DHTT air raid siren with a rotatore and single motor inside of the circular housing atop compared to the half circle on the average 500 SH or SHTT model. This on Wikipedia (Not what I usually use but I HAD TO DUE TO SO LITTLE 500 DHTT RECOURCES) said it was unfonfirmed to have a thunderbolt style rotator So I did what I do best and Made a version of it that would instead be belt driven and is connected to the siren either way. This was hard to make, not because I Couldn't model it or didn't have the recources to model it but because I scoured the internet for manuals & other stuff in a short period of time and decided to just go and search it in google and use the Wikipedia link and looked at the rotator's unconfirmed specs. Better than nothing tho.
