Interesting electronic unit. From the label information, we think it was manufactured in Philadelphia, Pennsylvania in 1950. Contains numerous electronic parts, including carbon composition resistors, capacitors, fixed coils, and oscillator coil. Each unit contains a 5703 subminiature tube, all branded Raytheon that we have seen, and a 7 pin miniature tube, tube number and brand varies.  The exact style of parts may vary slightly, but all are the same design.
Outer white cover is cardboard, bottom appears to be a phenolic base. We don't know if these are used or unused, so we have listed them as used. Items have dirt and discoloration due to their age, and normal cosmetic defects from items this old.
Nominal size
: 4.75 inches long, 2.5 inches wide, and 2.25 inches high. Item weighs approximately 4.7 ounces.
