According to this: http://en.wikipedia.org/wiki/Blast_pen
either 150 feet (46 m) or 190 feet (58 m) wide and 80 feet (24 m) front-to-back.
Although the pens were open to the sky the projecting sidewalls preserved the aircraft from lateral damage, with 12-inch (300 mm) thick, 9 feet (2.7 m) high concrete centres, and banked-up earth on either side, forming a roughly triangular section 18 feet (5.5 m) wide at their base.

Thanks. I am starting on their construction. The Actual base has taken shape as I carved out a base/outline out of balsa. I am going to mould the stuff on top of that. There is going to be an inner bunker as used in the E shape pens

Change of plans. I am making an Acrylic mould, designed out of Prodesktop 8. I will then vac-form molten plastic out of the mould.
Look forward to seeing it John.
