Is a quart 2 lbs and a pint 1 lb?

I have a 1 qt (6000 series - like Brad's , above) and a 1pt (5000 series) as shown in Sec 7, Page 5 of the October 29 1954 Truck Data Book. There is another 5000-style air-cleaner that had a non-ribbed top-cap (might not be a 1954).

I also have the more common 3100 style (216D?) and would like to see a 216G.
