Parker Duofold Senior streamline De Luxe
Hi Fellew fpgeeks!! I am new here and wanted some help to id my red Parker Duofold. I believe it’s early 1930s as it’s a streamline version with 3 gold bands. The other interesting thing about this vintage Duofold is that on the barrel it’s has CO and a anchor mark so it’s Christian Olsen version but the nib is a two tone flex Penol nib. I kno us Duofolds we’re sent to Denmark but expected a Parker nib and not a penol one. Any ideas? Any help to identify this model will be great. Many thanks. Once I learn how to post pics Here I’ll upload them.
