As early 70's Raleighs were known to change dropouts, fork crowns, and lugs on frame and fork during the same model year, and weren't exactly consistent on their kit, it isn't necessary, and probably isn't even desirable to have the same components as OEM. Besides, people that actually rode them typically upgraded components before they left the shop.

Lots of period correct components that would work well with that frame.
