The PAT PEND referred to the U-shaped tab construction (http://www.freepatentsonline.com/3215306.pdf)
All of the tabs in GEN III were U-shaped.
Tops had indentations for structure and were seen with & without “smiley beads” around the opening. Examples below. Please submit the following with your post:
