This is an Officiall Remake of the my Thunderbolt that i made

The Thunderbolt siren was a supercharged electromechanical siren produced by Federal Enterprises, which later became known as Federal Sign & Signal, and finally Federal Signal. The Thunderbolt has seven chopper levels, or voltage settings, that allow the pitch to be adjusted on the chopper, which gave the benefit to use lower or higher tones depending on the terrain and surroundings. The Thunderbolt can come in three port ratios, 5 Port single tone, or 4/5, and 5/6 Port dual tone. This siren was invented in the late 40s/early 50s as a cold war siren to warn the public of an air raid attack, later to be reissued as a multi-purpose disaster siren for weather, chemical spills, fires, or anything else that may deem appropriate. This siren went through many changes throughout it's life, and made quite a reputation as one of the best sirens in the market.

Thunderbolt 1000:
The Thunderbolt 1000 is a single-tone siren. The 1000's chopper has 5 ports. The rotor is the same as that used in the Model 2, as well as the same motor. In retrospect, the Thunderbolt is said by some to be a Model 2 with a horn and a blower which it essentially is. The chopper is little more than a Model 2-240 with the legs, stator ring, stator, and intake cone removed and the stator replaced with a chopper cap, which was a mostly enclosed item with a single port that connected to the back of the Thunderbolt's horn via. allen screws. The rounded rotator pre production models of this siren built were single toned sirens as well. This model was the first model, but was later optional; 1000 being the only model from 1952-1953, optional from 1954-1990.

Thunderbolt 1000T:
The Thunderbolt 1000T is a dual-toned siren. The 1000T came in 4/5 or 5/6 port ratios, which correspond to minor 3rd and major 3rd intervals, respectively. 4/5 variants are typically found in some of the oldest 1000T models, where 5/6 later because the standard around 1958/1959.

Thunderbolt 1003:
The Thunderbolt 1003 uses two solenoids that are attached to the throat of the horn. Each solenoid has a gate that closes off one row of ports on the stator. They are used to create alternating steady, alternating wail, pulsed steady, and pulsed wail signals, which can be used as a fire warning. Otherwise, it is identical to the 1000T, but used the 5/6 rotor only. Although the 4/5 port rotor is compatible, it was never offered originally. The 1003 entered production around 1959, and ceased in 1990. It is noteworthy that the 1003 was the last production unit ever built. The last sirens went to a township in Michigan, however all of them were removed and replaced around 2009.
Thunderbolt 2000:
The Thunderbolt 2000 is a variant from the 1950s with a blower powered by a gasoline engine. This unit was offered in single tone and dual tone. The blower was powered by an Onan opposed twin cylinder, four cycle engine. The blower size can be implied to be a 6MC size, as the 2000s were built solely in the 1950s, with the 5M only coming out in the very late 1950s (Ca. 1959), thus making the possibility of 5M 2000s either anachronistic, or a parts swap job if any exist. Some cities ended up with some, notably the outskirts of Los Angeles, and Phoenix Arizona. Units also existed in Florida and Detroit, MI. Only one 2000 stands today in Los Angeles, CA. Some 2000s are in private possession in Phoenix, Arizona as well.
