This is a very nice example of the Parker Vacumatic. It was made in the USA and is date coded for 1944. This is the 3nd Generation model with the plastic pump filler. It is also a Blue Diamond model which meant that it carried Parkers Lifetime guarantee.
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. There were some crossovers on the dates as old stock was used up. Canadian models tended to lag behind the US production as old stock was passed to Toronto to make way for new stock in Janesville.
The pen is in very good condition throughout with minor marks and scratches commensurate with light use. The gold plating is a little worn in places. The imprint on the barrel is clear and legible.
The diaphragm has been replaced and the pen is in full working order.
The 14ct gold nib writes smoothly with a Medium line.
