And they came in this kit provided to Coca Cola bottlers. Compare the tall test vile that's in the kit to the one pictured in the 1954 newspaper clipping. Also notice the two clips mounted to the inside of the lid. I can't say for certain but I suspect those clips originally held a hydrometer ...

Cool. I quickly looked up 'Brix Test' and found: (I am sure you know about this but here is some info.) Degrees Brix (symbol °Bx) is the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass. From: https://en.wikipedia.org/wiki/Brix

iggy / Rich Yeppers - I saw that reference and dozens more just like it - but its all still rocket science to me! We know some of the bottles were intended for measuring the amount of syrup dispensed from the filling machines. But what about the taller examples that are not marked? The $64 question is ... Were the taller, unmarked bottles used in a similar fashion as the tall test vials? [attachment=Coca Cola Syrup Test Bottle Tall.jpg] [attachment=Coca Cola QC Syrup...(956x1100) (3).jpg]

These looong links are to some looong accounts about soft drink bottling. For some reason they open to the middle pages, but just speed scroll to the top for where they begin. They pretty much cover everything you ever wanted to know about bottling from the olden days to the present ...

P.S. ~ P.S. And if you use the search box that has "GO" next to it and type in something like HYDROMETER it will pull up numerous options you can click on that will tell you all about them. Or use the GO box to search for anything specific.

If I understand the term "Throw" correctly, it refers to the amount of syrup dispensed from a filling machine. Based on the marks on the other examples we've seen, it appears the line on the Squirt bottle is near three ounces. And if I'm not mistaken, the only size of bottle that Squirt was using in 1941 was seven ounces. I'm not certain how much syrup went into seven ounces of Squirt, but if the test bottle line is near three ounces, that seems like a lot of syrup to me. But to be fair and open minded, the term "Graduate" also relates to measuring, as in 'test cylinder graduate used for measuring a liquid.' Hey, squirtbob - howz about conducting a little experiment and see how much liquid the bottle holds when filled to the line. If you fill it to the line and then pour that amount into a measuring cup it should tell you how many ounces it is.

Bob, I heard from my friend who owns the Squirt throw and he said that it hold 2 ounces up to the line. The syrup bottle that you found on ebay would date from the 1960's and I'm quite certain there were formula changes by then.

Interestingly, the squirt throw bottle that I posted is from 1941. I have a chart for "Formulas for the NEW Squirt Base" for 1942 and it states "the following facts and directions pertain to all formulas: Throw 1 1/2 ozs. to each 7 oz. bottle." Perhaps the formula was weakened by 1/2 oz.
