It sounds like a daft combination of woods to me. The core does relatively little work and thus can be a light stable wood. So why is the core a heavy wood that's good in compression? Hickory Maple Ipe would prob be much quicker.
Maybe open it up and laminate some lead sheeting in the middle, that might speed it up >:D
If I had to guess the belly wood I'd say Lemonwood

Sorry, Del... but you're mistaken. This is a common misconception. The core wood does do work. Similar to the belly wood. A compression weak core wood will in fact make a bow weaker, with more set. Essentially, the two woods become compression belly wood, but there is an additional glue line. Basically, two proper glue lines are stronger than one. The concern with using a dense core wood (like ipe) is making sure the limbs (especially the outer limbs) don't carry too much mass. All else being equal, my tri lam bows are faster (by about 10-15%) than my backed or self bows.
Perhaps think of it this way... two pieces of wood glued together will be stronger than a single piece of the same thickness, and three will be stronger than two.
I have used ipe as a core wood more than once, and it makes a fantastic bow. My latest is this: maple back, ipe core, osage belly. 70" ntn, 1 1/8" wide at the grip, tapering to 3/8" nocks. 53#@28" and shoots 175 fps. Very fast, no hand shock, bow weighs 600 grams, 1/2" of set.

Fair enough, I bow to your experience.
But please note I didn't say it doesn't work. I said 'relatively little' and of course the work it does will be proportional to it's thickness and position relative to the neutral axis.

BTW, Nice bow :)

Very handsome bow adb! Soon as I get my new fastflight flemish installed on the warbow I will post pics

Well, I was able to email with Jim Boswell himself and he set things straight! He says his warbows are only made with two belly woods: hickory or osage.
Per Jim, my bow is indeed HICKORY-IPE-HICKORY and was made in October of 2011. That lays that to rest once and for all. Cool! Just glad to finally know what I got.

I wonder if the dense core is used to keep the hickory from crushing that soft maple belly !! Have fun with it !
