Teak Batten (or similar) (Harold hill RM3)

Hi there I’m looking for scrap teak batten about L70cm x W10cm x D12mm

I’m trying to fix a garden bench that’s rotted out on one strip end and to buy and it’s £40+ as they only sell like 10 strips and cost as much to post as the wood does.

If anyone can help me out I would appreciate that very much.

Kind regards

Jay
