Geiger-Automatenbau GMBH

Geiger-Automatenbau GmbH is a German pinball company in Sonthofen, Bavaria, that started in 1971 selling spare parts for coin-operated amusement machines and, by decade's end, turned to conversion kits: operators bought a new playfield, plastics, and backglass to drop into an aging donor machine, with the original circuit boards and sound hardware left unchanged.

Its kits reworked solid-state Bally machines — Stellar Airship (1979, from Eight Ball, a run of 200), Lady Death (1980, from Mata Hari), the best-known Miss World (1982), Dark Rider (1984, from Star Trek) and Fly High (1985, from Supersonic), most limited to around 150 kits — before switching to Williams donors for its last two, Dino Turbo (1990, from Firepower) and La Retata (1992, from High Speed). Pinball output ended there; the company still operates today as a parts supplier under the Geiger-Automatenbau name.
