Yes and all 3 would be covered on top, the Anti chamber by the big main capstone, the middle big one would have a stone [or wood] on top and be resting on the angled backstone [that's why it's at that angle] and the little back chamber would also be covered, and if the whole thing had walling up to the main capstone it would make another big space above the 2 inner chambers,
I may have misunderstood but if not . Zennor doesn't have an equivelant stone going from back to front creating two chambers as Roy has proposed for what I would call the backstone at Trethevy .
One other thing that effects both PT's and others is that there is no doubt that they had cairns , maybe up to the capstone in some cases but they needen't have went all the way up , and sloping sidestones could have been much as we see them today i.e. providing access and not necessrily "filled in ", why use them in the first place ? They could be an important focal point like no sidestones or the sloping capstone .

The sidestones look the wrong way around on a lot of portal tombs because they had something [maybe wood] against them [and on them], therefore sealing the chambers, you see it again and the main capstones didn't seal the chambers on loads, it explains something in the design of loads that hasn't been explained, the trouble is i know what i mean but am shit at explaining it very well -one more try- the strange angle of the side stones is the hold something and seal the chamber, it's a very simple design, i hope you know what i mean [they were probably made of wood].
