Again, there is no Bear Factory documentation that is known to me that defines the meaning of any of the stampings.
That being said, more than one 1950-1960s Bear Salesman has told me that the bows with a stamping (that is any stamping, i.e., star, 22, etc.) were discount priced bows, such as left over bows from previous year's models, blems, refinished returns, etc, that were sold at discounted price and with no warranty on the bow.
Also talked to dealers who sold the discounted bows including the top volume dealer of these bows at one time.
Also have Bear factory invoices that document the invoiced bow as a "second", and invoiced at a discounted price.
The only thing I don't have is a serial number on a bow that matches one of the serial numbers of the seconds that Bear sold, which would provide unquestionable documentation of a specific stamping. Maybe that will turn up someday, you never know, stranger things have probably happened.
