I just happened to be in the right place, at the right time to "Acquire "
wellover 6Tons of the pictured wood.

Mainly 40mm*40mm *3.6Metre lengths of Resin bonded, Straight Grained,
Birch Ply.

Lots of various thicknesses of half sheets of ply, some of it straight
grain, lovely for bending :-))

Paid only for transportation,the wood itself was free :-)) Total outlay £100

If you are South Coast UK and want some (Free), theres around 40 Tons left,
all boxed up.
