What is the standard length of the immediate post-war wire cap line of Sheaffer pens? A relative bought me a green stripe Sheaffer that might be a "Sovereign II" - white dot, wire cap band, triumph nib. It has the post-war type clip like you'd find on a Touchdown pen. But what is striking is how small the pen is - it's 5 inches long. Is that the "standard" length for these immediate post-war, wire band pens? Anyone ever do a guide on these pens?
