So Bammy’s grandparents/mother could have figured out what book they needed in order to get a number for him, because we all know he lets other people do most of the heavy lifting.
She wouldn’t have needed to bother with a book if Harrison J. Bounel was a customer at her bank. All she’d have to do is lift his signature card with all his info including his CT issued SS#. Remember, banks must report the interest earnings associated with SS# to the IRS. Granny had everything she needed. All she had to do was wait until someone died. Even easier if that person didn’t have family to report the death to the IRS.
