Your small picture appears to have 2 nose cones with a possible section for attaching between one and the fuselage. Enlarged, I was less sure if these parts were even part of a Long-eze.
Please give more information about what you think it is and how it is to be used. I have done a lot of repairs, but no actual building of components. If it were me, and there is no nose, I would use the plans to build a new one. Somewhere along the way I might discover why these pieces were/are not installed.
