Need Help

[BrugBond]

Greetings! I have a box from old film, very rare, I found only two films of this series in Internet. As far as I understand, they are all lost. Maybe someone can figure out who the actors are on the cover? And "starring" girls to. Maybe we can even find more of these films together, I’ve just been trying for three months to dig up something.
I thought the guy on the cover was Willi Montana, because Willie used the photo from this cover for his film "Willi, der K. u. K. Jäger (1990s)", but these are two completely different films.
I can also say that film used a music that was used by almost all studios of that time. Example movie "Dirty Devils" time code 59:20. This won't help much, but I'm still sharing all information I have.

Generally the HWS/Impuls movies are listed here. And I guess some or many of them are listed on EGAFD as well.

But not this one.
I have seen "Sex-Shop Dirndl'n".
It's from the early 1990s. Willi Montana is not on the boxcover but he appears in the movie.
But I did'n recognize any other performers.
