"Are you sure it wasn't a 10-S-668?
https://radioattic.com/item.htm?radio=0021023It looks very much like the 12-H-670 but has the same chassis as the 669."
You might be right about that one. They do look the same.
I know the 9S-262 was tagged wrong because I went to an antique store on S. Broadway in Denver one Sunday with my wife and we saw a dealer unloading the Zenith from his car. I saw the paper tag and thought wheee! a 12 tuber or some odd variant. I bought it on the spot. It was a mis-tagged cabinet, but still well worth what I paid.
