What I understand is the “Special” Mason jar was a short run production from 32-37..
the jars glass and shape is much larger than a modern wide mouth but still holds same amount of liquid. The glass makes it appear larger imo.
I wouldn't think so. I'm really surprised that most Ball jars I see don't have date codes or factory codes or anything besides a mould number. Sometimes the charts don't make sense. It seems like Ball jars are all over the place.
I agree. It’s seems to get more complicated over time to be precise. I have recently inherited an older canning lot assorted with paraffin wax and clear quart bags and boxes for freezing food along with 2 boxes of meticulously packed mason jars.
Some Ball, Kerr, Hazel-Atlas and to my surprise a Drey Perfect Mason which was another surprise. There are 4 ball “special” jars. Both new to me and never seen before.
I know the bottle was made by the Schram Glass company which was later absorbed by the Ball Brother Mfg Co.
