I've got a Raleigh Record Ace with frame number WF300037 a very similar number to yours. It is made from 531c was bought new in 1983 but may be an '82 bike. It has very similar dropouts,but under bracket routing that I have not seen on other frames, It has four cable stops with two short stainless flexy spiral tubes I am currently restoring this bike,but at the moment it is still in it's original light green paint with all it's decals.My brother bought it new and we still have the receipt and owners manual for it.
