Re-Originals has (3) different NOS lighters, each a different length barrel; 50mm, 57mm and 67mm. These are not cheap ($240), so before I take the plunge I want to be sure I'm getting the correct one. Also, McCann has lighters for $145 doesn't indicate if they're repro's or what length. Anyone have experience with his Dino lighter? Since I don't have any in my car, does anyone know which is the correct length?
