Guess the ink

When I need a break from working, one of the silly things I do online is play a game with other fountain pen and ink lovers.  There is a group of us who play "Guess the ink", where someone uploads a writing sample of a specific ink.  Then we all take turns guessing what it is. 

There are thousands of different inks out there and hundreds of ink makers.  Trying to come up with just the right brand and name can take a bit of time, but we are experts at it.  

Since I won the last round, I posted the above writing sample on the website today.  

Anyone want to guess what ink it is?
