White Ovens

I've finished the bulk of work in SketchUp for my Batch Box heater.  It will have two bells, as well as a white bake oven.  BUT, now that I finished placing bricks (in the electronic world), I find that my oven bell has gotten very large for the available space - about 3 foot cube.  And I had started with the supposition of a 17x17x14 high interior for the oven.  I may have to change that!

So I'd like to know - for those of you with White bake ovens, what are the internal dimensions, please? And what do you cook/bake in there, typically?

Thanks,
Randy

I would be interested to see if anyone replies with practical experience of a full sized white oven, although I have seen a couple of pictures, I dont think I have ever read a report?
