I've done something rather stupid with my 3457A. I took it apart to replace the battery, and then seem to have mislaid the screws that hold the thing together. As far as I can see, there are 4 screws in the base. The problem is, I don't know what type they are. Could anyone with a 3457A tell me the type - a photo with dimensions on emailed to me would be great. I'm guessing these will be an American thread of some sort. I can get these in the UK, although not quite as readily as metric. But of course its difficult if you don't know what you want.
FWIW, I decided not to change the battery. Having visited Keysight in February, their cal lab manager said if I asked for it, they would check the calibration of the instrument before replacing the battery, then replace the battery at zero cost*, then calibrate it. So I would get before and after data anyway. * This assumes the battery is not very expensive. If the battery was expensive, I'd have to pay for the battery. My 3457A has not seen a cal lab in a couple of decades, so I think it deserves a check over.
