I don't doubt you.

Turkish and English should be the same species, with the original from the
Caucasus.

There are (at least) three grades of walnut that I can visually
distinguish. These are the American, English and Eastern European
walnuts. Now I don't know what species they are for sure, but I can pick
them out in a pile or a finished piece and they have prices to match.

Now every reference to US walnut timber that I've seen describes it as
back walnut. Maybe a grafted J. regia is grown for the nuts, but AFAIK
the timber is coming from J. nigra instead. I don't know if these are
nut trees, separate stands of trees, or where the nut wood goes to.

The Turkish walnut is also a different sub-species to the English
walnuts. Walnut has a lot of variation here between sub-species, if not
entirely distinct species. As I said, there's a large project going on
near Oxford to study this, and to select the best cultivars for UK
timber production.

So what are you claiming here ? That there is no difference and I'm
hallucinating it, or that I'm mistaken over my species altogether? US
and UK walnut timber just isn't the same stuff to look at, or to pay
for.
