The reason I am asking this is because I want to do a 3D model of it. You can see it in this screenshot from The Walking Dead. At first I thought it was a UH-1H, but the main rotor doesn't look anything like a UH-1H main rotor.
It is a UH-1 Huey.
... in the first episode of this sci-fi horror TV series about zombies in Atlanta, we see a pair of US army UH-1 Huey transports, painted with 'air cavalry' insignia, have been abandoned in a hospital car park.— rotaryaction.com
Looks like the main rotor has sunk down, should be higher up. Maybe a salvaged gearbox caused it to drop. Otherwise it's the same aircraft.
