I almost forgot this wonderful GRIESHABER pen and I found it this weekend and decided to share it with my friends. As you can see it is a crescent filler ( still with the price sticker ) . Wich is interesting in this pen is its turning knob at barrel's end in order to lock the crescent and prevent any accidental pressure on the crescent and the consequent leak of ink !!! The pen is NOS and the gold filled cap band has some grim ( not brassed ) .
Of course that it would be nice to find a similar one in...RHR !!!
