The floor dealer that I'm working with just recently installed a Coswick display. Their floors are beautiful. They have (almost) square edges with an (almost) smooth surface that is virtually impossible to find in other prefinished products in the US. You can also get select and better. That triumvirate of square/smooth/select is actually impossible to find in the US in a prefinished product. I've been looking for months and months for something that is prefinished to replace what I found is a unicorn 17yo flood damaged prefinished floor (ie square/smooth/select). I don't want to go to the expense of finished in place floors. (Meaning: replace my, what were $20k floors with >$40k floors) The downside? Almost all of their products are oil finish. You can't have everything and I think I'll take it.

I know that this doesn't answer your question. I got here because I'm looking for the same information. :)
