Lansend,
That looks like the "modern workbench" I built from the $20 Lee Valley plan in 1984.
I don't have much since 1984, but I still have the wife and that woodworking bench, and I am doing gunsmithing on it today.
I made mine from Rock Hard Maple [$2/ board foot in 1984], but I can see by your darker colors you used something else or a mixture.
