Hi All
Brent replies to the Joshua's FAST MAIL query with:
"Actually S.H.Co is one of the names for E. C. Simmons Hardware. These 
is an old reference to this on the old tools archive."
Couldn't S.H. Co also be Shapleigh Hardware. There could be a connection
then because the Norvell is definitely for Saunders Norvell who was
the president of Norvell-Shapleigh hardware for a period at the 
beginning of the 20th century (like 1902 to 1912??) Shapleigh (think 
Diamond Edge) eventually was merged with, bought by or bought Simmons 
(Keen Kutter) later in the century.
