Pelikan M620 San Francisco, M600 14K Medium, inked with Montblanc Leonardo Red Chalk
My most prized Pelikan.
My first M600 nib bought in 2010 on the M600 Black/Green Striated, this medium is serviceable but nothing special, it writes wet, which I really like.
I am a fan of the cube shaped Montblanc bottles used for special editions that are not Writers Series. They are deep enough to cater for my largest nibs.
I am far more impressed with this ink this time around than I was last time I used it some 28 months ago, on that occasion it was used in a double broad nib that did nothing for it. This ink does not provide a great deal of colour variation but the reddish-brown colour is very attractive.
