Even Wookiepedia doesn't seem to have this information about the TIE Fighter from Star Wars. The original TIE Fighter's full model name is TIE/LN. A friend of mine insists it's "Tie-in". But no. I've always known it to be L not I. Wookiepedia also has it as LN, but no explanation as to what that last part stands for.
Does anyone know?
