I am starting this discussion to grow my knowledge of preserving jars in New Zealand.
Branding on the jars are in square capital letters
Heavy glass jar that uses the gold coloured band. I have seen these in Pint and Quart sizes. I have them in clear and slightly green glass. I think these were produced in brown glass during the war.
I have a jam jar with AGEE in capitals that may be of the same generation as the AGEE SPECIAL
AGEE Special Pint aqnd quart jars use the gold coloured band to secure the D1 seals. Those seals are still readily available after october each year. Look in Pak'n'save. Milly's kitchen has them too I think.
These Jars are very popular at the moment for wedding vases.
