Help Identifying this bike frame I recently bought this bike from a non bike person who didn't know anything about it. I've looked at thousands of pictures and hundreds of websites and I cannot find this frame. So, that means it is either rare, or junk. There are no markings anywhere. No serial number. There is a "1" and "B" stamped/cut on the drop outs. I don't know if this is some kind of logo. Pretty sure the frame is aluminum. Bike is very light. Most of the components are Gran Compe (crankset, seat, seat post, brakes, etc.) Any help would be appreciated. Hate it when I can't solve a mystery. Strange design without a seat tube. Three paralled tubes welded together forms the frame.
Since you guys have all been so helpful, I thought you'd like to hear the answer to this mystery. 

The bike was indeed stolen. I was able to find the rightful owner. 

The frame was custom made of stainless steel in Capetown South Africa by BouwerWorks. (So, the 'B' did mean something). This builder has apparently stopped making frames, or else, has stopped any kind of marketing. His website is down. But, I found his Pinterest Board  (look at the profile pic) and also found an article on a design site with info. 

Most of all, I'm happy that the owner is getting his bike back. 
Thanks again.

Adding a bit more info. SO, I found the owner first and that is how I got revelation on the frame. I have a friend that runs a local charity. Village Wrench - They go into neighborhoods on weekends and do free bike repair for those who might have no other options - they do a mentorship program to teach people (mostly kids/teens) how to work on bikes, learn leadership, learn job skills, earn their own bike, etc. -- I sent him a message with photos. He suggested a few other people. One of them knew the owner (who moved here after spending time in Capetown) and was aware the bike had been stolen. After we connected, he told me the story of the bike and how it was made. With that info, I was able to find the BouwerWorks info online. A bike is only worth what someone will pay for it. But Bouwer regularly sold his frames $3,000 and up. So this owner was happy to reimburse me the $175 I spent. That low price is the main reason I suspected it was stolen. I provided the name of the person who stole the bike. A police report was filed a month ago. But I don't think the owner is going to bother with pressing charges at this point.
