By the way,
https://en.wikipedia.org/wiki/Agfacolor mentions that Rollei and a German company named Wittner Film still manufactures 35mm Agfacolor (or, rather, cuts/slits film from larger, existing, stock), although a source is not given.
http://www.wittner-kinotechnik.de/katalog/04_filmm/kleinbild.php This one seems to be cut by the company itself, as it's in a somewhat 'home made'-looking canister without DX code. It's E6 though, so it couldn't really be Agfacolor, could it?
From the website:
>Gutmütiger Farbdiafilm mit hoher Farbsättigung, ausgezeichneter Schärfe und exakter Graubalance. Diese Emulsion wird auf einem kristallklaren Polyesterträger gegossen und ähnelt im Bildeindruck stark dem früheren Agfachrome RSX-II 200 Material. Sehr hohe Form- und Langzeitstabilität, gutmütiges Verhalten bei Verarbeitung und Entwicklung. Entwicklung (E6) im Filmpreis nicht eingeschlossen. Keine DX Codierung."Good-natured/benevolent (''gutmütig'' is quite a strange word I think) colour slide film with high colour saturation, excellent sharpness and exact gray balance. This emulsion was poured on a crystal clear polyester carrier and looks a lot like the Agfachrome RSX-II 200 material from the past. Very high form and duration stability, good-natured behaviour during processing and developing. Developing (E6) not included in film price."
This could very well be a lead to achieve the aesthetics of the photos I posted, altough sadly it's only in 35mm.
