Okay, so I received the two OM-1's. I could wish them to be in slightly better condition... one has some weird stuff visible through the viewfinder that is on the pentaprism - It kind of looks like separation of either adhesive or some sort of rot or fungus, around the bottom edge of the viewfinder. The other camera's viewfinder is clear. Both appear to work properly and the meters come to life with the proper battery. I think I'll need to shoot a roll or two to make sure they are functioning properly. The previous problem of a worn-out spring keeping the aperture sensing lever in the right position isn't a problem with these bodies.
They do appear to have a fair bit of mileage on them, and so do the lenses. Both are in good condition, but there's enough dust in the optics to see that they've been well-used. I don't think it's anything which will hurt photos.
