Was there a hanger that was chopped off of it? If so, this one makes absolutely no sense - fixie hipsters who whack off their hanger are not the type to be overly concerned about having a rear brake - much less, permanently brazed-on guides for one.

I also note the seat lug has been torched - were any repairs done around that area? That would expain the top tube stops having been done at the same time.

What is more, the guides are located for right-front/left-rear brake routing. Interesting.
