~1971 Phantom-F-108 [Phantom II-108] by オリエンタル興業 (Oriental Kogyo) [presumed]

Name: Phantom-F-108 [Phantom II-108]
Year: presumed ~1971
Company: オリエンタル興業 (Oriental Kogyo) [presumed]

There is currently only a single clue to this game existing, which accs2014 has shared:

I am assuming the game is by Oriental Kogyo because of the "ORIENTAL" written on the marquee.

We have seen this brand in other machines released by Oriental Kogyo:

    

Super Match

Magic Hat

Super-Scope - スーパースコープ

This game cabinet is an exact copy of Air Fighter:

1970 Air Fighter - エアーファイター by 関西精機 (Kansai Seiki  —  Kasco)

Here is Air Fighter from a different angle.  The image isn't great, but the perspective is perfect for us to compare it to Phantom-F-108.

This is a very mysterious photo.  The 3rd game (from the left) is an exact copy of the cabinet for 1970 Cycle Rider - サイクルライダー by 太東 (Taito).  The art is beautiful and psychedelic.  Maybe a company like Oriental Kogyo were releasing copies of other games?

I wonder if this was a taste location they had prototypes at?  I would love to find more evidence about this mystery..
