[MENTION=171383]agmetal[/MENTION] Gorgeous Roadster! Preservation for sure. This bike deserves genuine period parts, but I think any pre reflector Raleigh pedals would be fine. Also, the 70s fender reflector looks out of place. Genuine ones sometimes show up on eBay but the repros like the ones they sell at Yellow Jersey for 5 bucks look pretty good to me.
