Gun ports and fabric stitching are the sort of detail that separates a careful build from an ordinary one. This section is set aside for parts representing gun ports, the muzzle openings in a wing or fuselage, and the stitched seams of a fabric-covered surface as found on older and lighter aircraft. Moulded plastic tends to suggest both rather than render them, yet on the real machine they catch the eye. The listing is being built up, and what the two terms mean and how to finish a surface with them is explained below.
