Gareth! Unfair! £5 just 'cos it is a bit tired? I did a complete rebuild on one of these just for fun, not difficult at all provided you can get the clip and washer (I got 2 sets just in case). Even tired I would say £15-£20 posted and as you say, in decent nick £25 plus post.

I have 2 of them one marked Milbro the other Diana.
