Lane Perception Chairs Wood Mismatch  

Good evening, I picked up 3 Lane Perception chairs on Craigslist and they are beautiful. However, when I picked them up they looked all the same color and finish. When I went to strip them down for restoration though I noticed that the third chair was slightly different than the other two. Namely the size of the screw holes holding the chair bottoms and the type/color of wood.
I think two of them may be teak but the third seams to be walnut. Did Lane manufacture the Perception chair with different types of wood?
Thanks in advance.
