Original prototype folder http://raleightwenty.webs.com/apps/photos/ Original prototype folder General view The chain guard was one that was to hand when the machine was assembled so is the wrong colour. It has no stand or boss to fit one. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051454 106051454 Hinge As you can see it has 3 points of fastening. The upper most bolt (as it appears in the photo) is the pivot point. The near nut is holding a stud that 'hooks' into the hinge plate. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051455 106051455 Hinge View from above http://raleightwenty.webs.com/apps/photos/photo?photoID=106051456 106051456 Hinge Here you can see the knob is screwed down and the frame locked http://raleightwenty.webs.com/apps/photos/photo?photoID=106051457 106051457 Knob unscrewed Here the knob has been loosened. The bolt head has risen but a spring below the bolt head keeps the frame locked so it will not fold. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051458 106051458 Knob raised Here you can see that the knob can be pulled up against the spring tension so releasing the hinge plates. They can now be pivoted. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051459 106051459 Frame folding It should start to be clear now how it operates. The bottom of the knob clicks into the recess in the top hinge plate so even if the knob is loose it will not fold when you are riding. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051460 106051460 Frame folded from below What looks like a bolt is in fact a stud that is a tight sliding fit with the 'hooked part of the bottom plate. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051461 106051461 Hinge release When the hinge is closed it is necessary to pull up the knob to allow it to close. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051462 106051462 Frame locked A view of the closed hinge from below. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051463 106051463 Prototype stamp Quite hard to read but it looks like CD (either cycle design or concept design) although the 'C' is back to front with a 0 and 30 following. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051464 106051464 Serial No As this started life as a stock twenty it has a standard frame number. I have not looked up the number to date it but the later dates do not always follow a logical sequence. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051465 106051465 Saddle This was a prototype Brooks saddle. It seems to have lasted well and is probably the best preserved part. I have not sat on it so cannot comment on comfort. I am not aware if it was produced in quantity. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051466 106051466 Saddle Another view of the saddle from below http://raleightwenty.webs.com/apps/photos/photo?photoID=106051467 106051467 Head badge Triumph badge. Of no relevance as it would have been badged with what was on the line that day. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051468 106051468 Decal This decal was for a toy go-cart that Raleigh produced. As George Ellis was in Raleigh toy design prior to cycle design it was most likely a sample he had lying around and just put on to make it a more finished appearance http://raleightwenty.webs.com/apps/photos/photo?photoID=106051469 106051469 Handlebar controls The twist grip broke years ago when George's wife fell off and broke her thumb so a trigger fitted. The right brake lever is a self adjuster again fitted for testing. http://raleightwenty.webs.com/apps/photos/photo?photoID=106051470 106051470 Sample Bell Nothing really to do with the twenty but this happens to be on the prototype. Raleigh asked several companies to supply samples of bells. This was produced in about 2 weeks flat of asking by a Far East supplier http://raleightwenty.webs.com/apps/photos/photo?photoID=106051453 106051453
