The 3458A is still supported by Keysight. You can get a Keysight Calibration for $777.
If it passes Calibration, then you are eligible to purchase a Keysight Repair Agreement for $216 per year. You can (or at least you could) buy up to a 5 year agreement with a 5% (IIRC) discount. As opposed to a 'per incident' repair of $3099. Or at least as listed at Keysight US Website. I've done this with my 3458A's and will be investigating them extensively if I ever retire. Good luck.

Agilent was split off from HP in 1999. So whilst 1999 is not the latest year a meter could be badged HP, and still sold by Agilent, it would probably be 2001 - not all labels were changed overnight. I believe there was a period of a couple of years, where something could be badged HP, but still sold by Agilent. So that puts it at least 18 years old. There is a rule, https://www.eevblog.com/forum/testgear/agilent-hp-serial-number-confusion/ which I don't know if it's 100% reliable, that the year of the last design change is 1960 + the first two digits of the serial number (MY45044988). If that was so, the last design change was 1960 + 45 = 2005. But if the design was changed in 2005, that would have been 6 years after HP was split off into Agilent, so it would be badged Agilent, not HP. I suspect that the meter is made from at least two meters, which seems to be quite common on 3458As.
