I'm not sure if this matters, but the model of these I have is a F5U119v, these are F5U119-E, and the ones on Amazon are F5U119-VE. I don't think it makes a difference, and I know the Amazon one works just as well on a 1989 1391401 Model M, but just a heads up.
Anyone know for sure if they work? I already have 3 of mine, which is as many as I need, but I know some other folks would could use some of these.
