Rubbish. The sticker is still on my 14 year old washing machine.

Hell I've got a 55 year old piece of electronic equipment here with the serial number sticker still on it.

I've got a 65 year old FM radio with manufacturer-supplied circuit diagram still inside the case.

I’ve got a tube based oscilloscope with a hand written sticker saying service is due in the ‘40s. The important info is stamped metal (model, serial number), or internal paper stickers (field manual).

It still worked last time I plugged it in. I’m not sure if I’ll be able to find someone to calibrate it when the 40’s roll around again. :-)
