Rear Fender

[Speedy1959]

Hi All
the bike I am getting on Wednesday has a tail tidy on...
Im a bit old school when it comes to those..
Does anyone have a Rear Fender that they would like to part ex or sell?
I dont want to pay what they cost new as it seems bloody expensive for a piece of plastic..
I am open to suggestions as to where I could buy one second hand if you can think of anywhere (in the UK)..
Thanks in advance.
