Hello Paul, apologies for not replying sooner, I have been tied up with some other work.
I have 15 lengths of Peco g45 track. They were laid out on raised benchwork at our previous house, but never fishplated together, fixed down - or run over. So they are 'weathered' but not worn or damaged; a good wash down and you are away!.
Let me know if you are interested, how many you want and how much you want to offer. I can send you photographs if you wish.
