Have you any bits of black gutter/downpipe knocking about? (Mudeford BH23)

If anyone has a short length of 112mm (4.5 inches approx measurement across the top) round type black plastic gutter going spare I would be grateful for it. It would need to be a minimum of 25cm (10inches) long. I also need a short length of 68mm (approx.7inch) diameter black downpipe. This would need to be at least 40cm (16 inches) long. Both are needed to finish a job without having to wastefully buy more full lengths. Thanks, Trevor.
