Wow this is bad. I was about 13 or 14 years old and all I can remember is that they were Kodak chemicals. A lot of Agfa film but I don't remember for sure if the B/W was Agfa too-- I sort of think it wasn't. By the time I was in college I didn't have a camera and was taking a "break" from photography for reasons too complicated and probably too controversial to mention, but I did spend some time helping friends in the college darkroom. I remember jugs of chemistry there, but I don't remember what they were. I do however have the strong memory that I was the only one who freaking actually read the directions, and that was a big reason I "knew what I was doing" while they were flailing around and having problems.
