I’ve been digging around the wood database to see if I could identify this pine. I mentioned it’s heavy. It’s also still incredibly resinous. It really gummed up my bandsaw. Did I mention it’s at least a hundred years old?
I think it may be this:

But it comes from south central US. This is heartland Wales.
