Reed Organ

A reed organ, also called a pump organ, is a type of organ featuring foot-operated bellows which produce wind, and a hand-operated keyboard which generates musical sound. In the second half of the 19th century, reed organs became popular for their low cost, power of expression, and comfortable size, and came to replace pipe organs for use in church services. They also became common instruments in homes. Above the keyboards are several knobs called "stops," which can be used to increase the range of sound when playing.

Marimba

The marimba is a type of percussion instrument which is played by striking wooden bars with a mallet. It is known for its warm, gentle sound, characteristic to wooden bars. Below the bars are metal tubes which produce resonance. They come in varying lengths according to the bar's pitch. These resonators amplify the bars' sound, giving the music depth. The marimba has a broader tonal range than any other percussion instrument, and can play melodies and chords, meaning it is often used for solo performances.

Electric guitar 02

An electric guitar is an instrument that uses devices called pickups to sense the vibrations of its strings, sending an electric current through a shield (cable) to an amp, thereby adjusting the volume and quality of the sound. Electric guitars are used in music performances across various genres, and probably the most popular models are the Les Paul by Gibson, and the Stratocaster by Fender. Although electric guitars come in countless different designs and shapes, they can be divided into two main types: hollow body guitars and solid body guitars. This paper craft model is based on a solid body guitar, at a scale of about 1:2.5 that of a real guitar.

Helicopter

A helicopter is a type of aircraft that has rotary wings. The engine causes the long slender wings, called rotors, at the top of the helicopter to rotate, providing lift and allowing the helicopter to fly. Compared to aircraft with fixed wings, helicopters are slow and get poor mileage so they don't fly long continuous distances. But they can take off and land in narrow places because they have the unique ability to move up and down vertically, as well as fly in reverse, sideways and hover. For these reasons, helicopters have been put to use in many ways, such as for transporting cargo, conducting rescue operations, and for industrial aviation. This paper-craft helicopter is a standard single-rotor type.

Articulated Ladder Truck

Unlike a straight ladder, the Skyarm ladder articulates in several places, making it possible to avoid utility wires and other obstacles encountered during firefighting and rescue work. By attaching a fixed waterway to the ladder sections, a large volume of water can be deployed quickly and accurately. The Skyarm Sigma features a set of push-button jacks that can be extended to support the weight of the truck and maintain a stable, perpendicular platform, while the three-section telescop-ing ladder can play a role in rescue situations that require considerable horizontal reach. Because the floor of the platform basket remains horizontal, aerial operations can be carried out with added safely.
