Vlaanderen (Flanders)

I added this coin https://en.numista.com/catalogue/pieces25233.html to the catalog, but it's not possible to select Vlaanderen as the issuing authority. Would anybody of the mods be so kind to add this country ?
Thank you.

will do if you upload some nice images from straight above (obv. and rev.).
some data would be great, too (diameter, metal etc.)

pictures and data added
ruler = Karel de Stoute (Charles the  bold ?????????????)
greetings

hmm. since I do not have access to WC catalogs of 15th century I have to ask:
was Vlanderen parts of Belgium or France or else? where to put this in?

http://en.wikipedia.org/wiki/Flanders_(county)

if I understand correctly, flanders was an independent county, part of the low countries...

is it listed as "Flanders" in the WC catalog 1400-1501? that's the question here
