Also I find it hard to believe that Stanley publishing all of its catalogs
wouldn't list the option on some catalog page in some catalog somewhere.
Since they were selling things by the doz or more, they weren't a direct to
consumer mail order catalog, and printing was arguably more expensive or at
least a PITA in those days I would think these plus sizes would have made
it into one or more of their annual catalogs
