Looks like a early 1970's Raleigh sports, the type of brake leaves that bike has where only put on the raleighs for a few years in the early 70's after those the quality started dropping. most my 70's Raleighs have those because I think they are interesting.
Compair that Raleigh to my old black one, both sports and not much changed over the years back then, these where great daily use worker bikes.
