“what you have there is a Platignum Gold Nib deluxe Pressmatic.These were top of the Platignum range back in the 60's/early 70's and not cheap at the time.The Deluxe is double jewel but they also did the Gold nib with a single cap jewel and as a cartridge pen.The build quality is not brilliant but its not really bad either.”
