Wow, call me a tube-weirdo, but some of those boxes are really cool! I really like that Duovac one, it's beautiful. The Sylvania is certainly the earliest one I have ever seen, I'm trying to figure out what is depicted in silhouette in between the trees...a woodland nymph talking to a robot??? The Ace box is fun, with its slogan (Ace of the Air), and the RCA UY-227 is a box variant I have not seen before either.
If I remember to bring my camera home from work tomorrow, I'll have to take a few pics of some of my more-interesting and rare tube boxes.
As for testing the WD-11 tubes, others more knowledgeable may chime in, but I think you could use a pair of alligator clip leads and a D-cell to see if the filament lights up. You know from my prior post that the fat pin is the plate, so you only have three combinations of pins to try to see which is the filament (in case a base diagram is not able to be quickly found on the web). Since it is a filament, and not an indirectly heated cathode, the glowing filament should be obvious.
Nice haul, and have fun!
