I’m pretty sure the dark wood in this desktop organizer I just made is Swamp Mahogany.

The light wood looks like swamp mahogany, I have done some turning with it, it is hard and heavy but reveals some marblesk grain. The salt and pepper grinders are made from it.


The light wood in this is Curly Maple. Looking at some other possibilities for the dark wood, I’m convinced it’s either swamp mahogany or african mahogany. Here’s a link to more pictures of this desk organizer:


There is a USDA report (1963) that will fill in the ‘no data available’ blanks except for price. https://www.fs.fed.us/psw/publications/documents/psw_rp009/psw_rp009.pdf The properties listed in the report for plantation grown wood were slightly lower, except for MOE.
