Most likely Vahlok's mask was the wooden one. As stated before, it was likely to be used to keep Miraak contained in the pocket dimension (or past, whichever you believe). This is supported by the fact that the mask's only enchantment is to teleport there and back.

Obviously, the masks in Solstheim show resemblance to Mora and look like they were hammered out from the original masks.

And Vahlok was a powerful, trusted dragon priest, as well as the one responsible for keeping Miraak imprisoned in the pocket dimension (again, or past). He wouldn't have defaced his mask as he never followed Hermaeus Mora's influence.

That's my take, somebody else please rip it to shreds if it's awful.
