The frame is worth 10 times the bits attached which are probably worth less than the WD 40 needed to get them off! Frame needs a total refurb I reckon and I am not fussy. What ever you do take photos at every step or the frame becomes yet another newly painted , unidentified , supposedly 531 but has new stickers, "race " bike.
Sorry to be harsh but that sticker in its original state has all the value. .
It could be made a nice bike with some second hand bits, especially some better wheels.
