Sorry I just took my KCS apart as I needed the blue roof pieces and large windows for my MOC I am taking to brickworld!
I just don't have the parts to put it back together again.
I did get to campare them side by side before I took the KCS apart though. It is amazing how stable the King's Castle is in comparison when you pick them both up. KCS is quite a bit larger though but definately not as solid.
