Can anyone tell me  where the serial number is located on the Calisher and Terry breech loading military rifle?  Is it the number on the bottom outside face of the trigger guard? This number is also stamped onto part of the loading mechanism.
I would also be grateful to receive  information about William Terry, the date he patented the loading mechanism and the role played in this business by other members of his family.  
 
Many thanks  
Jonathan

To avoid confusion I suggest all further discussion on Calisher & Terry is continued here.  
 
Thanks.
