I just read a chronology of the Ball zinc caps and am surprised to read that NO zinc cap actually had the BALL logo on the top of it until the 1930's.
Is this still an agreed to fact about these old caps?
[This list does show the Ball name on the glass LINERS during two different time periods... First in the 1880's & again in the 1920's]
So if I want period correct zinc caps I need to hunt up something other then BALL caps ;-)
[oops, forgot my own rule for quoting references ... the list is found within the May 1990 Ball Collectors Club newsletter and it gives credit to :
