I have everything you need mate. All correct period undamaged Raleigh cotter pins, bolts washers whatever you need. But there is an easy way to remove cotter pins without damaging them. You shouldn't ever hit them out with a hammer. This will almost always "mushroom" the ends or bend/snap them. Remove the nut and washer, then put a socket over the non threaded end, then put it in a vice, making sure the pin is in nice and parallel so it doesn't bend when you tighten the vice, then tighten the vice by a few turns and it should pop right out undamaged, if it doesn't come out after a few turns of the vice you probably need to re-position it as its not in straight, if you tighten it too much and it doesn't come out then its probably not in parallel and your probably bending it, which you don't want because then it will be even harder to get out. To make this a lot easier to do strip the rest of the bike down and get all the parts off the frame so it's easier to hold and position it in the vice. I hope this helps.
