I took my wife to breakfast after dropping off the grandson, then headed over to a small town nearby with several antique shops in a row. Down in one dark little corner I found a cache of tools. Lots of hand planes that were reasonably priced, but ended up picking up a saw clamp, tooth set, and a handful of files for about $20.
All of the files had some buildup in them, but still have good teeth, did a quick cleanup with the file card and then sprayed them down with some penetrating oil to break up the surface rust on them. Will give them a good cleaning later.
Also found a little deburring/counter sink tool and a stone/jig for touching up planer blades.
