SSE

SSE was never produced -- it exists only as an unsigned, undated Williams Manufacturing Company playfield drawing (Model 54) for a baseball-themed single-player game. The surviving sketch appears unfinished, with numerous erasures, including reworked passive bumpers.

As designed, the game called for two reversed flippers, a single pop bumper, four passive bumpers, two slingshots, and possibly a gobble hole positioned between the flippers.

Because the drawing was never turned into a production machine, no physical example of SSE exists, and its designer is not identified on the surviving documentation.
