A closer set of pictures of the drive train, the head tube, rear drops, the upper side of the BB would be good. The seat stay cluster

Is the front derailleur brazed on?
What are the mish mash components?
Is there pantographed Rossin on the stem?
Seatpost diameter?
Headest?
Is there "R"s carved into the head tube lugs on the down/top tube?
Are those internally routed brake cables?

I am leaning toward 1985/86...closer look would help with either SL, SLX, etc...
