Where can one buy a Mirro pressure cooker?

I found it! I also have a 12 qt Mirro Pressure Canner/Cooker. Someone has downloaded the original instruction booklet in a PDF format online that includes the recipes. It's a 25 page booklet that would be best printed on both sides of the paper if you have that kind of printer. Don't worry about finding pages 4 & 5. They are blank anyway.

Go to:

Scroll down to "Mirro Pressure Canners and click on: "Click here for a Mirror Pressure canner manual." They spelled Mirro with a r but it's just a typo.

Hope this helps!
