A couple of new films, since the turrets were completed, They've now been salted away prior to efforts commencing to build some prototype shapes in geodetics. To that end, the jig has been extended by 300mm to reflect the scale change from the original 1:4.5 to new 1:3.7 scale. This scale change arose due to concerns as to clearance between the outside diameter of the planned engines and the cowls. The change in scale may also assist in getting rivetting tools into gaps in the alloy channel.
