Looking for the rubber feet (2 at the back) and rubber bumpers (4 on the front bezel) for my HP 859x spectrum analyzer (the ones of the 856x are compatible as far as I can see). Those that came with the unit emit a strong chemical odor that I just can't tolerate.
Experience with other such rubber items tells me it's not going to go away, no matter what I do with it (wash/let soak in IPA, wash/let soak in detergent, try to replace the scent with something else strong like lavender). Weeks long exposure to strong summer sunlight sometimes works, but it's the beginning of winter here, can't wait that long.
So if someone had such items in odor free state and wants to make me happy (and some money)...
