Type name used by manufacturer:
Hamilton Antique Light Face Extended Reversed 
This is the Hamilton cut.
It is unlikely that this face was only produced by Hamilton, as all manufacturers offered a reverse version of their types, but the Hamilton and Baker catalog of 1887 was the first to show a specimen of this type.
