Well this has been a pretty long time in the making, I had hoped to get to this last year but between life and the pandemic, things just got too crazy. Today though, I met up with Brendan W and Will (TNT1001) and we are pleased to announce that as of Saturday, April 3rd 2021 the Atlanta Stockade Mobil Directo is confirmed to exist and has been photographed by drone! The entire siren, sans the upper horn and rotator belts/chains appears to be present, but on its side. The good news is that all of the noise making bits are present and it is an 8 port model. My best guess as to why the siren is in this state is that the siren was set to be removed, however with its size and weight, the removal crew simply took the parts that were easy to remove down and laid the rest of the siren on its side so that it would not be easily visible from the ground. The old stockade has now been renovated into an office complex known as Glencastle but despite these renovations the siren still remains. This is the sixth gasoline powered Mobil Directo known to still exist which is kind of mind boggling given the fact that Atlanta had 25 of these at one time. I am still almost at a loss for words, it is incredible to know that this part of the City of Atlanta's history has not been wiped out for good. Without further ado, here are the photos:

Just for fun, I stopped by the last remaining Thunderbolt in Cobb County, located at Meridian Brick on the way home. A total of 30 were purchased from Dekalb County in the late 80s/early 90s and made up most of the Cobb system until their replacement, mostly in the early 2010s but with a few stragglers hanging around until 2016. This was part of the Smyrna system in Cobb County, which now consists of Whelen Vortexes but was formerly comprised of STH-10s, a few WS-1004s, and two Thunderbolts. Here are the photos of that siren:

Overall, I am thrilled that this discovery has been made and I am really thankful for all of the help from the siren community! I hope that you enjoyed these photos.
