R-U-M-B-A

The R-U-M-B-A pinball machine, manufactured by Coin Game Manufacturing Company of Chicago in March 1932, is an early example of pure mechanical (PM) pinball, from a period when games relied entirely on mechanical elements with no electrical components.

Advertised dimensions varied slightly between 1932 and 1933 listings - roughly 54-55 inches long by 28-29 inches wide - suggesting minor production or marketing revisions during its short run. Little further documentation survives about R-U-M-B-A's specific rules or objectives, which is typical for many small manufacturers' pin tables from this era.

R-U-M-B-A's rarity and the limited information available about it underscore how many early coin-operated amusement games from the early 1930s have been lost to history, making surviving examples of interest to collectors and historians studying the earliest days of pinball.
