I only have the 120 apron,. I bought my Kodacraft 50 years ago brand new. Just pulled it out, still in the box w/instructions tonight. When i bought it, it was just for kicks. Never used the apron. Since I had already been using my Honeywell Nikor tank when I bought it, I laughed at that apron as a recipe for uneven development. although I DID use the tank with a steel reel 3 or 4 times. It only takes 4 days to pour out all the developer and pour in the stop bath. IF you don't mind chemistry leaking out all over everywhere the whole time. I've kept it in the original box all these years. Still looks brand new. Still smells like it did when I first bought it. Smells like vomit, if my crude description is permissible by the moderators. I still wonder if people actually used that thing way back when? To me it was always a nostalgia piece and nothing more.
