Anyone have info on the non-Duofold "Big Red" Parker Lucky Curve Senior (1920's single band, orange celluloid). I'm well familiar with the plethora of rubber Duofold-style (or should we say Duofold is styled on the simple Lucky Curve, which did precede it) pens, such as the 25 (which is about DF size) as well as many larger and smaller models. Less familiar with the orange plastic Lucky Curve non-Duofold, looking to be mid 1920's or so, given single cap-band. Info appreciated. -david
