Here are threee pictures that may be of interest.
1. Photo of early Kodak making equipment. Kodak no longer uses closed kettles. No need to in a clean room.
2. Photo of Sample Coater. I believe that this is an early one as the ones I used were about 2x larger. The hopper is in the center foreground and is the extrusion type.
3. Kodachrome processing machine with Dave at the controls. The generation of this machine is unknown, but with Dave there, it must be K-12. The first Kodachrome process had 28 steps and K-12, which came later had 18.
4. Process control. Here are Mitch and Ron working on one of the vAg controller boards for the automatic feedback loop system. Two people who worked on this are not in the picture. Ron, on the right, got my office when I retired
