I have an old Wedgewood D-20HP stove that someone can have for parts if they want. It does not have a regulator, but burners, tubes, lid, case, etc is all there. They guy who had the pop up before me did away with the regulator and had one off his bottle or something.

It works, I just replaced the outside stove with a gas grill since there are so many no-burn days in the Arizona forests, go tired of not being able to grill a steak when I wanted it.
You pay the shipping or come pick it up. I'm in Phoenix, Arizona.
