Submarine - サブマリン by 三共 (Sankyo)

Name: Submarine - サブマリン
Year: 1969 or earlier (probably mid-1960s)
Manufacturer: 三共 (Sankyo)

I only have a single reference to this large installation by Sankyo, and that's the 1969 Machine Directory.  The clever cut-away in the picture reveals what is obfuscated by the control panel.  I assume it has similar gameplay to the similarly-sized 中村製作所 (Nakamura Seisakusho) and セガ (Sega) units.

This is a bit of an outlier for the "Periscope Series" since it doesn't seem to have a physical periscope, but it is hard to ignore when lined up next to the other machines in the series.
