I actually had a word with guy doing the texture today. I've been wanting to showcase the thing for a while now, so he should be able to give it a nice texture and finish it up. Soon.

I tried to reply on your profile, but could find no way to do so. Anyway, here is your answer: yes there is a model of the Centurion MK I that is completed and animated. It is currently being textured. Once the texturing is done, it will be released. Then, I will model the MK III turret for it.
