The VACUMATIC are in my humble opinion a big group of pens or a big type of pens , each one of them with its own caractheristics ( size , color, shape, cap bands, nib, clip, pattern and so on ) and for that reason each one of them with a special charme! During the VACUMATIC era, a lot of celluloid plastics were offered by DuPont to Kenneth Parker who had to evaluate and discuss ( together with his staff ) which colours and patterns had the chance to be a commercial success. The solid colours were not an option but as usual some prototypes were made. It´s interesting to think that too many years after, this option was taken to produce some British, French and Danish Duofolds!
Along the years I had the oportunity to buy some of these so rare pens or even mockups ( without nib or feeder ).
So you have now the chance to have a look at some of these beauties.
PS once again I would like to thank to my friend João Pavão Martins who worked on this photo; the colours you see are the real ones!
