Yes, I'll grant the seller a Skyline cap, but the barrel doesn't look like a Skyline.
When I saw my first Skyline, I thought: What an ugly barrel! Then I got one (or a dozen, to be honest) and found that the design is perfect when you post the cap. And such soft nibs!
This looks like an ordinary semi-torpedo shaped barrel with a Skyline cap. Oh, and Skyline prices seem not to have increased, except for a few wishful sellers. A good "starter pen" for people just becoming interested in fountain pens and wondering why people insist that "vintage" pens are better than the many current-production Chinese pens. Easy to replace the Skyline sac, and not so expensive that I worried when a Skyline shattered as I cleaned it with sunshine cloth.
Context: who knew so much about "plastic" when the Skyline was produced, and I suspect that Eversharp's design team had no idea that 70 years later people would be fiddling with Skylines. Subtract 70 years from 1940 (for simplicity) and imagine what Eversharp's engineers would have thought about a top-line dip pen from 1870!
