Those are really hard to find. As a matter of fact vintage pens are getting fewer these days. I am looking for a few pens, a Doric, a Skyline CA, a Stainless Steel Fifth Ave. Even though steel cap pens were cheaper than gold, they're more difficult to find than gold. The highest on my wish list is a gold Parker 51 ballpoint pen.
I don't know if it's the economy's picking up or vintage pens are getting popular. There is just not a lot of pens on Ebay. And when they appeared, people are getting ultra aggressive. Even real junk are going for good money. I have over 200 pens. So I know pretty much how much they should be going for. But I was blown away every time at the last minute. And I thought people only buy Mont Blanc.
