The manufacturer�s original playfield drawing (not shown here) had its bottom section cut away and missing, but the top of the words "9 Sisters" can be seen. Any date and signature would have been below that. Williams experimented with score reel scoring in their single-player pinball machines during Oct-Dec 1953. 'Nine Sisters' was one of six games made in this way. They went back to using bulb scoring in 1954 and didn't use score reels again until they began multi-player production in March 1955.
