TWO VINTAGE KERR QUART SELF-SEALING TRADEMARK REG MASON JARS

These are great quart sized jars! They are each paired with Vintage Ball Lids that are Zinc porcelain lined. AHK 505 is imprinted on the bottoms. Research says they are ca1970 so about 54 years old. The Zinc lids are a great find! I have photographed everything - enlarge for better views. These have been in our family, but I have no first hand knowledge on specifics.
