Need some help.  On a brass plate on the stock it has the following...
   A(then some sort of symbol)MOR(then either E or R).  On top of the barrel, it says MF GRANT, then underneath of that, GOWANDA.
  Any Ideas?  I am at a loss.  Don't know the calibre and cannot find any other markings on it.  I just know it is older than dirt....Thanks
