Both the chainguard and (I think) the saddle were aftermarket replacements. Hercules, Robin Hood, Triumph and several others were made by and essentually the same as the Raleigh Sports, although the forks were different than the Sports-- flat crown vs. the funny pipe thing.

If you are interested in originality or something more appropriate than the Bontrager saddle, you could put on a sprung, leather Brooks saddle.
