That was a great help! Thank you! Poking around the board, I found the original thread where discussion of the Pennsylvanian's repro boxes first started. In it, it was mentioned that the material was, "...ash or other suitable material.", and mention was also made of white oak. I will price it both in ash and white oak, and explore other options with the sawyer once I settle on one.
This seemed appropriate to include.
