If you look at first picture, First 2 bikes you see are homebuilt, 3rd one in with big tires is a Harrison, one right next to that is a Taco (but might want to really look it over as that woud be easy to replicate, and as you can see someone could build bikes), and the one behind the row on its own is an Arco
