Hi Everyone, Another unknown vintage fountain pen from Japan. If anyone knows anything about this pen I would like to know more. This pen has "Trade Mark Super" engraved on the barrel with an image of Mt. Fuji. It has a ink window at the barrel but is a squeze converter (I am about to repair). The nib is steel and reads: Special/ Bests/ P/ Smooth/ #3/ Pen. Thank you for any information, Pen_Padawan
