same pachinko/different comp.

[1930artdeco]

Hi All,

Found something very interesting yesterday while I was looking at Pachinkoman's website. He has a Sankyo with the exact same playfield as my Mizuho. Although the colors and design are different it is the exact same layout. So here is my question:

1) Did Sankyo buy out Mizuho and use leftover pieces?
2) Did Sankyo supply Mizuho with parts?
3) Did Mizuho Supply Sankyo with parts?

Either way I think it is interesting.
