Question on Radio Tubes

[vendo81]

Today at a garage sale I ran into a dozen or so boxes of old tubes. There was also 2 boxes of very early radio parts,dial parts etc. Most of the tubes (about 250) were new in their boxes as in the first photo. Looks to be mabey 30's or 40'S? One box has about 50 tubes that were individually wrapped in newspapers dating from 1948 and 1953. I've included a photo of a few of the wrapped tubes. Are these still used or just display tubes? Are they from the 30's or earlier? Thanks...
