“American Standard", was not in business until the 1980's.
Noll & Co. owned the mold that was housed at the Burt co.
Burt made them and shipped to Noll.

Once Noll went out of business, someone else could have bought the mold and used it awhile.

Buglars burned many of the older Burt records, I have forgotten the year.

I had a list from Burt that listed when all the molds they used were made and when they went N/A. It also showed if new molds were made, that is why you see two versions of some molds such as the Hub.

I loaned that list to a Club member without keeping a copy. Big mistake, he claims he can't find it.

Burt records will become available someday.

You can see the exact day the arrowdie mold went N/A in my Arrowdie article. That record came from the existing Burt records.
