Would put good money on it being a 531c Raleigh. all identical to mine from 83. What size is the seat post? Maybe not marked or impossible to measure of course. tony Oliver has 653 and 531 seat tubes having 27,5 mm internal diameter but often using a 27.2 due to less than perfect brazing marginally distorting the tubing. 531 ST has 27.2.
He suggests 531/653 tubes need a 27.2 seat post or 27.4 if silver brazed to high standards where as a 531 st would use a 27.0 pin.
Don't know if this helps or confuses.
Still reckon it's a Raleigh.
