Parker Duofold Jr Lucky Curve Fountain Pen Vintage 2 Gold Rings USA

You are bidding on a Parker Duofold Jr. lucky curve vintage fountain pen. It is the trademark red/orange color. The gold clip says "Parker pat ser 5-16." The pen body says "Duofold Jr lucky curve geo s. Parker Janesville, WI fountain pen USA pat 4-25-11." The nib which remains unbent says "Parker Duofold pen made in USA." The pump pushes in and out but is a bit rusty and loose. I have not tested it with ink. The pen measures 11.5mm x 1.5mm. It comes without a box.
