This is a celluloid and potentially silver alloy blow filler fountain pen with a reminiscent look to that of a Watermans Golpheresque. The nib writes extremely smooth with a perfect amount of responsive flex.

There is a personalization on the body "Jos L. Theisen".

The pen is in rather worn shape, but has plenty of charm and character to go with it. The cap finial plug is slightly inset into the inside of the cap, but does not change any performance of the pen.

I personally deeply enjoy this pen as a writer!
