Original cubic curves and measured coordinates from the reference top view; upper half reflected for symmetry, nose up, uniform final scale. Reference dimensions: 59.35 ft (18.09 m) length; 46.26 ft (14.10 m) span; 15.12 ft (4.61 m) horizontal-tail span. The source illustration has small drafting inconsistencies between views; its top-view geometry is retained. This is the earlier short-wing Merlin IVA, not the 17.37 m-span SA227 Merlin IVB/IVC. Native SVG with transparent cockpit/nacelle/control-surface cuts, no external resources. Decorative aircraft identification artwork, not an engineering drawing.
