A short while ago I bought a number of Pelikan pens from someone including a tortoise one. It was rather big and I am always confused about the model numbers (M400/M600/M800/M1000) so I went to my pen repairer and asked him about it and he told me that it was from the 2010's and confirmed it to be an M800. However when I came home I noticed that it had W-Germany on the cap ring, from which I knew this was used only at the end of the 1980's. After some reading up I now know that my pen repairer referred to the 2013 remake of this model. My collection scope is focused on Montblanc, so I want to offer it for sale and I would like to put an appropriate price tag on it. So the question is how much do you think something like this is worth?
It is in very good condition. It also had an OBB nib which I know a lot of people like (personally I prefer Fine).
Many thanks in advance.
