West German made Pelikan fountain pen 12c-500

Thank you for viewing.
This is a West German-made Pelikan fountain pen, model 12c-500. The nib size appears to be HM.
(It's a little difficult to see, but the letters at the base of the nib seem to read HM.)

Piston filler: You twist the back of the pen like a screw to draw up ink.
I bought it 12 years ago and used it for things like writing New Year's cards, but I haven't used it much recently, so I'm selling it to declutter.

I used Pelikan Royal Blue ink in it.
The nib unit (which can be removed by twisting) and the inside of the barrel have been soaked and cleaned for over a day. However, please be aware that if you use a lighter color ink, there is a possibility that a slight blue tint may appear at the beginning.

There is no box or instruction manual.

I hope you will consider this item, understanding that it is a used product as described above.
