What does the Series H mean on a Fox Model B

[FourBee]

Just acquired this Savage Arms , Westfield Massachusetts,  Model B , 20GA. SxS with a ventilated rib barrel.  After the 'FOX B' it reads  'Series H'.   Was wondering what that stands for?
It's in very good condition.   Anyone know how old it may be?   Ser# B 891_ _ _

I just came across an old article that may give a clue to the meaning of the 'H' Series of the FOX Model B.
The 'H' represents features found on that particular gun.   
These are : The gauge, 12 and 20.    Light Engraving on the Receiver.       Standard grade Wood. 

I'd still like to know how old this one is.

May be getting somewhere.   Savage Arms gave me the address of a Mr. John Callahan, whom they gave all their records of serial #'s and information.      Just received a letter from him today, stating that for a small  'FEE'  he would research all the information on my gun.   Just send him the Serial# and Model.   He has records for both Savage and Steven's.    The research fee varies from  gun to gun.   Anywhere from $25 for mine up to $30 for Stevens and unidentifiable guns,  and $30 to $40 for the old ancient A.H. Fox guns.

So, I put a check in the mail with the required info.    Takes about six (6) weeks to get an answer.  I will try and post it...
