Hi Thomas, i can find suppliers of 'sapele' wood (assume that's the stuff) on the net, but they all seem to supply large quantity. My advice would be to try kit manufacturers, like JoTiKa Ltd. They might be able to help.

Cornwall Boats do a similar range of timber for modelling, just be aware that there is a £2.50 surcharge on orders including wood, so get all you need in one go if possible. Cornwall Boats Timber

This is the link to the constructo web-site Constructo Timber Guide provides a useful chart showing colours of different woods including Sapelly, but doesn't give info about where to buy in UK.

You might try phoning Cornwall Boats, I believe others have had really helpful replies to their enquiries. They are Constructo stockists.
