perimeter frame i.d

[T.J.Brearley]

Today I picked up 2 perimeter frames which I'm unsure on the brand of.
One has a ycf logo on the head tube and the other has no brand but has a billet back bone. I also picked up two lifan 125's.
I got all this for $50, I'm just trying to get id on the frames and some insight if I got a good deal or not

the swingarm with the triangles looks like its from a ciniworx
