It's a Rayne Demonseed (if you know the Rayne brand, it's good), which retailed for $175 (currently discontinued). It's a heavy board (I don't recommend it if you don't lift, seriously, it's a large board (44" length) and pretty heavy (10 lbs), so I'd recommend taking weight into account before buying the board. It's very sturdily built (it's meant to be a downhill board but can be used all around campus). See the product page here: http://www.atbshop.co.uk/longboard-decks/rayne-demonseed-deck

Here's a video review of it from the Rayne company: https://www.youtube.com/watch?v=eBxz63IhLbc#t=44

I've attached pictures of it. It's been chipped on both sides and has some scraping from the good ol' days of crashing going down hills / Stanford parking structure at high speeds. The scraping adds to the badassery of the board anyway. I'm selling the board for $100 OBO.
