That was the first thing I tried. The way the bolt sat in the stem it wouldn't work, just push the cone out of the stem base - which it did.

Jealousy is so unbecoming on you.
I saved you this week. The PX10 in D.C. wasn't (didn't even have the chromed stays shown in the Craigslist picture). The Eddy Merckz may have had 531 tubing but the sticker was facing backwards at the top of the seat tube. He also had a lightweight 531 touring bike with 600 components but at $200 it wouldn't work for resale and my stable is full.
This is what it should look like if you ever get it unstuck.
Bottom photo shows the wedge with a couple of turns on the bolt and the bolt flush in the top of the stem.
Nice pictures. Only the bolts and cones remain. I cut the head tube free and soaking overnight in ammonia turned the whole stem black. The flag decal got trashed. I finally cut the stem to free the headset. Looking at the cut it looks like a solid piece - I cannot tell where the stem transitions into the fork.

Three days in 85F or greater heat with ammonia (changed out twice daily) plus 15 minutes with a rubber mallet each day with no results.

Note that the rust you're dealing with is probably at least partially electrolytic rust between dissimilar metals which basically formed a weak battery, so if you essentially drive that battery backwards you should be able to undo some of the damage.

Thanks, I'll keep a link to that site. The oxalic acid solution did a fair job on the surface rust. It's moot now.
I did get the seatpost out intact and it turns out I can use it (size 27) for my all Campy Alan Shorter bike. It now has a high water line from the oxalic acid so I'm not sure how I'll get it shined up.
