the PRESTO jar and closure

I believe these pieces have always been together but don't know for certain. Mom had 3 of these, all the same, and all with the same 2pc PRESTO lid on them -- but there could be a chance that the lids themselves were originally intended for canning jars and just happened to also fit the larger square bottles. I have absolutely no idea what the bottles first held, if they weren't actually intended as canister type containers.

The glass jar itself measures roughly 7" high and 4-1/2" square and has a neat sorta art-deco diamond pattern on 3 sides with corner decorations. On its textured bottom is a maker's logo with the numbers 7, 3, and 3 surrounding it.

The lid is a 2 piece affair with a 2-3/4" round glass disk, which is indeed embossed with markings that could more suggest a canning jar than storage canister -- the name "PRESTO" and words "TO OPEN INSERT KNIFE AT NOTCH >>>-->" would make me think there's at least a missing rubber gasket or something, and that there coulda/shoulda been some kind of 'vacuum seal' involved at first. The aluminum part of the lid is made of stamped aluminum, and bears the words "THE PRESTO JAR AND CLOSURE ARE APPROVED BY" with the logos of the "Good Housekeeping Institute" and "The Household Magazine".

PLEASE SPEAK UP if you have any idea what this otherwise nifty old bottle and/or its lid is really supposed to be?!! Meanwhiles, I think I'm going to take a clue from what Mom did with the one of the three that she kept -- fill it half full of pretty glass marbles and set it in a sunny window! ;-) :-)
