Zinc canning pot and warmer

Nice couple this morning consisting of an old zinc canning pot and an old bowl. They both come from the farm where we picked up the milk churns: the very old canning pot was patented by Weck; it is from the 40s, it is branded and still has the old label with the instructions. You could lift the lid and take out the tray where the canning was placed. A thermometer could be inserted through a hole in the lid. It is 40 cm high! The old bowl keeps it company, also in zinc, it kept warm under the covers as a foot warmer in the long, cold winters.
