For anyone considering this, I personally was quite pleased at both the prompt shipping speed and results from the film, purchasing 2 rolls of Portra 160NC and one of the Konica 160 for respooling on 616 backing.
I developed my first "test" rolls in a rather stretched soup of a Unicolor kit that I mixed last week. The Kodak film was shot in a reliable Ansco Clipper Special "half frame" 616 camera with an f/6.3 triplet while the Konica film was tested in an unproven Kodak Six-16 "Improved" full frame 616 folding camera with a 124mm Kodak Anastigmat of Tessar type.
I tended to overexpose the Portra by 2 stops, simply because it's a preference of mine, and is what I do even for fresh Portra. Still, I did a few shots using exposure settings for ISO 160 as well. The entire roll came out wonderfully, sharply defined with wonderful contrast, and little to nothing that I could detect in so far as base fog. I did a couple of hasty scans to share (pardon my scanner quality) below.
I only had vestiges of late afternoon light in a dreary winter landscape with which to shoot the Konica color film, and tried to overexpose that as well. Expired ca. 2002, the film displayed appreciably greater base fog than the Kodak upon developing, but the scans were salvageable. As mentioned above the camera is unproven, and shows signs of a light leak and some need for better focus collimation (or better focus estimation on my part) before being used again. Despite the vast technical flaws of my shots, I was able to get a decent idea of the color rendition of the film, which despite the age and fog, is still easily scanned, and while on the cool side to some degree, doesn't seem to suffer from an excessive shift of the color palette as I've tended to get with other Konica films of similar vintage.
