My not-quite-mother-in-law asked me to identify this Parker pen she's had amongst her antiques. Problem is, I'm not really sure what it is. It's short. About 118mm, I think. I'm not sure if it's a sub junior, a debutante or something else. And I can't figure out what year it'd be. thoughts? The gold cardboard box in the photos might help, too... Thanks, all!
