Only Sandtroopers understand the importance of water jugs in every day life, & for the backpacks.
So today is the Tupperware part a.k.a radar dish in backpacks. But which one among the two? Which size?
Managed to get two of these for comparison.
Exhibit A & B:
Some indentations at the bottom. Same for both A & B:
4.4 inch = 11,176 cm
5.25 inch = 13,335 cm
To me, A here is the more accurate one. B just seems a little bit too big. A doesn't necessarily be in that brownish color as i've seen them in white too. But please do make sure of the measurements.
I am not saying these are the EXACT screen used ones, i don't know how many Tupperware variations they have in the 1970s; but they are "close to screen accurate".
So troopers, the next time you get yourself one of these water jugs, do call me and send it to me lol .. OR keep it for your backpack. It's "vintage".
