Parker 51 Dove Grey Vacumatic, with Lustraloy Cap with Parker Chrome-Plated ‘Plain Arrow’clip Imprint on barrel "Parker 51" made in USA
Parker had tried a number of new filling systems, ment to replace the Vacumatic filler and in 1946 an uncommon Parker "51" was introduced, the so called Red Band "51". It was in most aspects a re-designed button filler. It was fitted with red threads by the filler and it was also advertised as the Red band "51", as opposed to the Black band "51", which had the ordinary Vacumatic filler.
