Tail Construction: The Tail No. 33 Mk I is a hollow steel plate cylinder open at the after end, with an angle ring welded or riveted onto the forward end and drilled to take the assembly bolts of the rear body section for attaching tail. Hand clearance holes give access to the assembly bolts. |
|
The Tail No. 52 Mk I has a cone with hand holes for access to the securing bolts, and a cylindrical strut, attached to the cone by six fins which are welded to the strut and cone. |
