Worth, the canner w/o the gauge is probably a Mirro. We get questions about it a lot. The weight rocker on the top controls the pressure. As long as it is rocking correctly, the pressure is fine. I personally use weights on my Presto along with the gauge. The gauge is more to tell that the pressure has gone all the way down to zero after the heat has been turned off before opening the lid. I like the weights method.
