Boneshaker78 - Just hazarding a guess on the seat stay aspect... It almost looks like one of the old seatstays that were spit on the small end to all a drop out to be fitted up into it. Now in a rushed build where one mitred the stay for the joint up at the seatclamp before realizing that the tube was rotated 90 degrees off... so the worker just slaps it on the saw and cuts a new slot??? Running in a little additional brass to fully fill up the gap would have hidden the goof... if they had cared (which is not evident in most of the frame)
