Here is a super nice original 1920's Parker Lucky Curve Duofold SR. "BIG RED" fountain pen. Clip says PARKER Pat. Sept 5-16. Double gold-brass ring on the cap. Nib possibly is 14K and has what looks like the letter F or maybe P.I cant read it, I dont have a loop to see that close. It also says Parker Duofold Pen and the letter. NO cracks. NO breaks. Great piece. The shaft has the makers name, Duofold, Lucky Curve and a pat; date on it as well. Thanks and have a Blessed Day
