I've previously scanned a copy of this doujinshi and posted it in https://e-hentai.org/g/1086422/4d8559381e/ but the quality of that one isn't that good as it was done in grayscale.

This is a different scan (in fact from another copy of the doujinshi, as the old one had been destroyed after being scanned). Besides being done in color, I've used 600dpi.

Studio Sharaku has been around for quite some time (yes, he is active; he had a booth at Comiket 93) and he haas reprinted his doujinshis more than one time thru the years. As the previous one, this is a copy of the 2000-3-3 edition. https://e-hentai.org/g/75223/6f5ec5c69d/ is the 1994 one.
