SAILOR RARE FOUNTAIN PEN BALLPOINT PEN COMBO

THIS IS A VERY RARE SAILOR FOUNTAIN PEN AND BALLPOINT COMBINATION PEN.  THIS PEN HAS A BALLPOINT PEN IN THE END OF THE BARREL THAT IS PROPELLED BY A KNURLED RING ON THE BARREL.  I AM SURE A REFILL WILL HAVE TO BE MADE FOR THIS PEN.  THE ORIGINAL REFILL IS INCLUDED BUT DOES NOT WRITE.  THE FOUNTAIN PEN IS A AEROMETRIC AND CARTRIDGE? FILL PEN.  THE CONVERTER IS INCLUDED.  THE PEN HAS A FINE POINT 14KT GOLD NIB.  PEN HAS EXCELLENT COLOR AND IS IN GREAT CONDITION.  THERE IS A LIGHT STRESS HAIRLINE IN THE LOWER END OF THE BARREL THAT IS NOTHING MAJOR BUT MENTIONED TO BE THOROUGH (SEE PHOTO).  PEN COMES IN A SAILOR BOX.
