...I should have gone a-readin' before I rather quickly restored one this morning.

Like a lot of folks, I watch eBay for good deals on serviceable classics. I don't really have a collection direction, and as such don't seek out certain pens and bid them up- the pens I've won on eBay are generally dirty, unrestored, little information, mislabeled, with decent nibs and usually have me as the only bidder. Very slow way to get these pens, but I'm after cheap serviceable pens that'll give me some experience repairing pens while building a small and diverse collection of vintage pens.
I won a Skyline, $10 shipped, with the usual vague description and bad photos. First, I was pretty bummed out because the pen wasn't all that dirty, everything was in working order, *and* the nib needed no adjustment. The sac was somewhat hardened, but still filled, though poorly. Dipped it and found that it was a stub! It's very snazzy. I ended up spending 20 minutes to clean it up and resac it, definitely ship shape.
I had no idea the plastic was fragile... I used a lot of force to take the section out with my hands. I guess it's a good thing I managed not to break it.

And I took it out and put it back in a dozen times.

The only thing wrong with it is the cap- perhaps it's shrinkage as discussed above, but it seems that the nib bumps up against the metal at the tip of the inner cap, or something else- I have to be pretty careful when putting the cap on, or keep the derby loose.
Are stub nibs on these puppies common? It sure writes nicely, that's for sure! Really quite a treat- very smooth. My first stub, even.

Regards,
Aaron
