This is a nice clean example of a Parker Duofold AF Button Filler. It wwas made in Denmark around 1945 by Christian Olsen who made and distributed Parker Pens under licence. Olsen's Company was the first to strike a deal with Parker back in 1904.
The pen is finished in Coral Brown and marked with the Olsen trade mark anchor as well as the Parker marks. It is in excellent condition with minor marks and scratches commensurate with use. The gold plating is in good order with only light wear.
The pen is totally original and has been fully serviced.
The nib is a lovely Fine which writes smoothly. These are lovely pens and quite scarce in good condition.
