The tubes look quite uninteresting, but the cases are
indeed nice. It
seems using tape cases for parts is a common behavior - I have seen it
many times elsewhere. In fact, I have a friend that has oodles of parts
stuffed away in RCA Bizmac tape cases (extra deep!). 
The cases look like some that IBM had as well.  I've got a couple of
them with screws in them at my folks place.  I got them when I was a
kid at the "Tek Country Store" (Tektronix surplus/junk store).  If
they are the same kind of cases, they are quite nice (the best I've
ever seen).
