A closer look at the tube cap, and the note accompanying the tubes carried by Lindbergh, which gives a little more detail about the contents one could expect to find in AE's tubes if in fact the technology had remained the same or similar.
Here's a
very detailed 1935 article by Meier himself along with field notes by Lindbergh--full of info, pictures and diagrams. Just found it, so I don't yet know what treasures it holds.
A long shot (and for that matter, I don't know when the US military initiated fingerprinting for servicemen), but if Noonan did collect samples and, per the procedure described, seal the tubes with adhesive tape, his fingerprint could conceivably be on the tape and tubes.
