no such thing as an original 13.5" metal frame
so whatever you saw was either a repo, or a 15"
I should rephrase that then.
I saw a used globe frame that was all rusted but at the time I never knew they were any particular size and I didn't have a pump or "Yard Art" to put any globe on.
I am looking for the smaller size to fit my 5 gallon pump top but now that I am advised, It looks like they don't come small and original from your post. Thanks for the info
