Gentlemen
Many thanks for your quick responses. I had already located a "Ken Holden" basic plan and that is what I am now also able to view in Outerzone.
Fuselage, tailplane, Fin and engine nacelles have pretty much survived. Strangely, hardly any of the wings remain.. However, I do have one aileron and a wingtip. From these pieces, together with the Ken Holden plan, I should be able to "wing it" and complete the model quite comfortably.
Once again, many thanks for your replies.
