Has anyone reported variations in the actual machines? The reason I ask is that Williams seemed to be pretty fast & loose with the stencils on video games. Defender (video game, not pin) had a left and right side stencil, but there are a lot of them using a single stencil for both sides. It results in the soldier on the side facing the back of the machine.

Not even trying to defend/condemn Twisted Pins, but I think Williams were just cranking games out as fast as they could. Stencil issues/variations weren't considered important.
