Damn, eBay.
The PreWarAuctions.com homepage is "broken" now, with all sorts of modern stuff showing up (it was showing pre-1930s before). Maybe I'll get rid of it then...
The other categories still work fine though. There is also a link at the bottom of each results page that will take you to eBay to see all of the results since the output is limited to 200 results max.
Browse by Set, T206 for example:
