Judging from the package logo and the Hough Avenue address, these tubes were manufactured sometime after 1955 and probably prior to 1970, but that's little more than a guess.  

The GV3A-450R indicates that this is a Hi voltage regulating diode, with a nominal voltage of 450 volts.   It's unclear what the R designation indicates and it has not been found in any of the available Victoreen catalogs.

These tubes have what may be a 4 digit date code printed on the side of the tube, but at this time we have no information regarding the nature of those numbers or any codes used by Victoreen.
