Old Dorff's also used the real deal Mahogany, and no doubt certain other cameras. Wisner was a harpsichord maker prior to his camera venture, and did beautiful wood joinery on his Technical Field cameras, which are on the heavier side of his lineup, and quite pretty. I'm sure he would have chosen his material carefully. By contrast, his lightweight and Expedition cameras, though pretty too, didn't impress me as being very durable or stable; I'd be afraid to drop one on a pillow.
Even wooden masonry levels were once made with Caribbean pattern grade mahogany. That's why they didn't warp. All the "mahogany" levels made today do warp. All the proper kind of trees have already been cut down. And besides, it takes about eight years to properly cure it.
Now many substitute mahogany-like species, mainly from central Africa and Southeast Asia, are used for a variety of items. For picture frames, I once experimented with a fast-growing sustainable hybrid product called Lyptus, which resembles mahogany in color. But like Ebony wood, it sinks in water, eats up shaper carbide fast, and is ridiculously heavy - not a good camera choice.
I have some lengths of real Hondouran mahogany on my moulding loft, but it's not pattern grade.
