I believe you are right, all the WFL interiors I have seen were African Mahogany with solid 1 ply maple re-rings. How would you describe the difference in sound and performance between the 24" WFL 3ply Mahogany bass drums verses the 3ply Maple/Poplar/Maple Ludwig bass drums that you have owned and played over the years?
Roger, the WFL zephyr drums are 3 ply makeup of mahogany, poplar, maple, they are a little less brighter sounding with less volume, than the maple, poplar, maple drums but I think it is more to do with the bearing edges on the bass drums, I have other WFL kits and their bass drum on those kit roar simple because of the sharper edges, The toms from zephyr era kits have always left me unsatisfied as the bearing edges on them are completely flat. the drums are just dull sounding.
