We are looking to buy mechanically animated manikin bowling arcade games. They are the games that are basically shaped like a pinball machine, but have an enclose (mechanically animated) bowler figurine that actually bowls a ball down a small lane. You can move their angle, and bowl the tiny ball down the alley.
Williams made a “Mini Bowl” (in 1970), “Ten Strike” (in 1957) and “Ten Pins“(in 1957). Plus Sega made a “Pro Bowler” (in 1972).
