I think it's a 1971 Raleigh Competition. I have one of these in my garage from 1967 and i'm restoring it - i just rechromed the fork. The fork weighs almost nothing, it's way better than a raleigh international fork, which weighs like, 2 lbs or more (more than any other fork I have !!)
These bikes also had a time period when they had chromed nervex lugs but i think the whole-frameset chroming is an aftermarket add-on.
