Hi. I got this pen for about $8 of an auction at Tradera (swedish eBay) I have tried to find som information about the pen without any luck. The thing i have found out is that the swan symbol should be the logo for Mabie Todd. Is that correct? The modell is a Standard Pen and is a piston filler with a nr. 4 Ero 14k F nib with some flex. Does anyone know something about this pen modell? Best regards Pether Olsson
