Hey Memphis. I just wanted to drop a dime on something I saw on your craigslist.
This Proteus could be pretty awesome.
Proteus isn't far from my place here and is a pretty awesome shop. The current owner, Jill, is pretty rad and Ben rips my legs off every wednesday during the wolfpack. That being said, this frame might be pretty awesome on its own accord. You see, Yamaguchi worked for Proteus for a while making frames. Without some poking around, I can't say he made this one, but it might be something to look into.
