Thanks to much for the response @Mark P!
I guess I could've been a little more specific. I am a woodworker and sometimes collect old wooden moulding planes, I hear they're a dime a dozen there but here they can be quite collectable. Anyhow, sometimes these tools are in decent condition with the exception of these narrow "quirks" (slivers of boxwood placed in the sole of the plane), which can be worn/broken/chipped/missing. You can see one circled in the photo.
So I do not need large pieces, maybe something 6"x2"x1". I wanted to use European boxwood to match the original materials as much as possible, also for its exceptional denseness and smoothness. I understand if you want to hold onto your supply though!
Cheers,
Andrew
