[Request] [Bounty] 全開学園 (DUKE) /Zenkai Gakuen (Duke)

[Haiyami]

So I am looking for Zenkai Gakuen by artist Duke. It was a hentai manga from the early 90s. Most galleries have been lost to time and all that remains are illustrations art pinups and fan art. I take it that the only way to obtain the original mangs is to find it in Japan and manually scan it. Not only am I putting up a request. I am placing a Bounty on it. Images below are illustrations.
