I recently got a Presto canner from my dad that he said my mother either never used or used maybe once. I also have my own Presto. Last week I had both gauges checked by someone from my county extension, but I never saw the washer to my dad’s in the box so when she checked it all out there was not a seal around the gauge, and the rubber ring fit all the way through the hole. I did then find the washer for my dad’s, but the rubber seal does not sit above the hole, it sits flush with the top of the lid. I don’t see any gaps but I am unsure whether this is an acceptable fit or potentially dangerous. Whereas on mine, the seal is mostly above the hole (first photo). The second two photos are of the lid in question, top and bottom.
If someone would be able to let me know I would greatly appreciate it! This is a 17 qt Presto pressure canner and cooker, model 01750, product number 21-429 circa 2000. On their website to look for parts the only 17 qts they have are models 0175001-0175006 and I can’t find any corresponding number on the box.

My nagging nature would likely make me go get a different gasket from the local hardware store but this is likely fine.
You can test it without jars, just bring it up to pressure and see if any steam or water leak out of the hole.
