Older electricity meters are entirely mechanical, and therefore had to be manufactured to a high standard to ensure accuracy over a long period of time. Due to the high costs of manufacture, they were normally recalibrated and refurbished rather than simply being disposed of.
New electricity meters are small electronic devices with no moving parts, and if broken are most likely scrapped, as it will be cheaper to have a new one made in some far away country, rather than attempt a repair.
