This is a very nice example of the very desirable Parker Vacumatic Oversize. It was made in the USA around 1934. The Oversize was the biggest Vacumatic that Parker made, it is longer and has a bigger girth than the standard Vacumatic range. It was an expensive pen in its time and is now very rare.
This is the 1st Generation Oversize model with the lockdown pump filler. The first generation Vacumatics (1932 - 1936) were fitted with the metal lockdown filler and had a short blind cap, the seond generation (1937 - 1941) were fitted with the speedline filler with the longer blind cap, the third generation (1942 - 1948) were fitted with the plastic filler, again with a longer blind cap. The later Oversize models with the single cap band were rebranded as the Vacumatic Maxima.
The pen is in good condition throughout with minor marks and scratches commensurate with use. The gold plating is showing signs of wear, especially on the clip. The colours are clean and vibrant throughout. The clip screw and blind cap screw have the correct emerald pearl striped jewel, The imprint has worn away.
The diaphragm has been replaced and the pen is in full working order.
The original 14ct gold nib writes smoothly with a Fine line.
