Maybe we should agree to disagree here, after going through this on the 'New signs' thread a while back.
My point then was, basically, how long was it since those signs were replaced?
 It feels like it wasn't that long ago, so, perhaps, were being replaced for some other reason?
I have to hold my hand up & say that I never noticed the general condition of the them (riding too fast....not!😂 ) & perhaps they had seen better days,
I just expected them to last a bit longer.
Maybe, as has been alluded to, they will all appear on an auction site, like previous ones, but I'm not suggesting that as a reason to replace them...honest!
