I just picked up an older Presto pressure cooker at a garage sale. It looks to be in fabulous shape, was in the original box with the original manual, and all of the parts (gasket, pressure gauge, valve, etc) look to be in fine condition. I spoke with the original owner, an older woman who's been canning forever. She's used it every year for decades for her canning, but is moving to a new home with no garden.
I purchased it for $10, and then called up Presto. Apparently this model was made in 1974, and you can still get parts for it!
Does anyone else use an older canner? If so, are there any quirks I should watch out for? Safety issues?
