Monkey Bash

Monkey Bash is a rare and little-documented electro-mechanical pinball machine credited to Bally Manufacturing Corporation, the manufacturer that dominated the pinball industry for over five decades. Bally's own records list Model 803 only as a "novelty" release with a 1967 project date, and it doesn't appear in known Bally parts catalogs or production lists, so it isn't even certain the game reached full production or what became of it afterward.

As an electro-mechanical machine, Monkey Bash would have used a combination of electrical relays and mechanical components typical of Bally's late-1960s output, though no details survive about its specific theme, designer, or feature set.

Because so little documentation exists, Monkey Bash remains one of the more mysterious entries in Bally's catalog. Its very obscurity - an entry on a production list with no confirmed release, artwork, or design credits - makes it a curiosity for historians and collectors trying to piece together the lesser-known corners of Bally's history.
