Someone asked what I meant when I said "low wax". It appears that the 60s globes had a lower level of wax for the 52oz. globes. Globes (L to R) #2 and #4 have "normal" levels of wax seen in Centuries from the 70s on, and globes #1, #3 and #5 have the lower-level of wax and were made in the 60s. The lower level wax globes, I've found, are see on Squiggles bases and Centuries that have the soft copper two-piece bases.
