Guys,
I noticed a local restaurant is remodeling and they have a dumpster full of old booths. Always on the lookout for free wood, I browsed it. The booths are mostly plywood construction with some cheap 2x6 pine trim but they are internally framed with plenty of this hardwood. I have no idea what it is. I snagged a few pieces and planed them to take a look. I'm giving links to pics for some help determining if it is worth the effort required to tear it all out and pull staples. The manager said I could have all I want.
It doesn't feel dense like oak, it is surprisingly light but still hard. It is very pretty when planed with long flowing soft grain and it varies from red to nearly white.
Here are the pics.
