Till a few years ago kodak put out a printed "professional products" catalog that had all the weird stuff in it and was fairly complete. As digital took over they dropped it, along with a lot of the products. Most of the stuff still available could be found online though. But it was downhill from there. I can't find anything on their website now and you can contact whatever they call the professional products division now and hope you get someone that might have a vague idea about the product you are looking for and whether they still sell it. Last time I heard portra 160nc 10" x 6' cirkut film was available by the roll, but they don't make it easy to figure it out. You have to hunt it down.
By removing or hiding your products list online, and not publishing it anywhere, you pretty much are taking away the demand for it as no one knows you are selling it. My only conclusion is they want to not sell these products anymore. It's sad to see kodak destroy their own market, but they clearly are either completely inept or making a conscious decision to shrink the specialty film market. I can't even easily figure out what aerial film is being made. I'm assuming it's a conscious but stupid marketing decision. Wouldn't it be smart though to have a complete online products list. I can't believe it would be that hard to maintain. Anyway, hope color cirkut film is still made. If so, I wonder how much longer.
