Ain't that the truth!
I am glad I got that replaced as the old washer literally broke in half when I was trying to pull it apart for the replacement parts. Actually, I think 1/2 of it disintegrated as I couldn't really find it that half! It would have sucked trying to get the bits out of the tank if that hand happen when I was pulling it out or if the washer popped while the tank was under pressure!
The pins are not what you would call in good shape but they should hold until it is someone else's problem. The Stainless Steel & Washer should last much longer than 100 years (pins, doubtful). I'll need to remember to dab some oil on it when I am done steaming it - perhaps that will slow down the rust on the pins.
