Taller pint-Ball Perfect Mason????

[towhead]

I have (2) pint size Ball Mason, drop A, double L, Perfect Mason jars. One has the off center Perfect Mason with a 10F on the bottom, and other has the centered Perfect Mason with an 8 on the bottom. The off centered 10 F one is about a 1/2" taller than the other. Also, the neck area is noticably different. Does anyone know why they are different? (All my other ones are like the #8 centered one. Thanks for your replys! -Julie Pic 1:

Your jars difference is because the jar on the left ( 10F) is an aquired mold jar.

It was formally a DREY jar that Ball Brothers aquired when they bought them out.

Hi Julie and David,

I don't mean to be disagreeable but this isn't an acquired mould or a Drey mould. The reason one jar is taller than the other is that they were made on different machines. The PERFECT MASON on the left with offset embossing was made c1913-1914 on the early Owen's machine. (smaller base scar) The jar on the right was made between 1915-1923 on a later version of the Owen's machine. (larger base scar)

Ball bought out Schram (the parent company that produced the Drey jars) in 1925 and none of the acquired Drey moulds were ever made in blue glass, only clear. The Drey reworked moulds have the word PERFECT offset but it is offset to the LEFT of MASON. All of the PERFECT MASON jars with PERFECT offset to the RIGHT were made c1913-1914 from older Ball MASON moulds where they added the word PERFECT wherever it would fit. New moulds were produced for a newer version of the Owen's machine in 1915 and the embossing was centered as we commonly see it.

Some of the PERFECT MASON jars with the 1910-1923 script style were made on the older Ball-Bingham machine and they are a different height than either of these. When Ball couldn't keep up with customer demand for jars, they often fired up the older machines to help produce the jars needed to fill orders.

Just another reason Ball jars are so much fun to look for. []
