Latest find - MP 18 1 but info on code/dates?

[Bigsieuk]

Lucky to come across a deactivated MP18 1 recently here in the UK (pics to follow). 2 questions;

1) Does anyone know how they are dated to serial number
2) The snail drum magazine has an adaptor half way along the infeed rather than just the conventional snail drum for a luger?

Regards

The MP18 primarily served in final stages of World War I in 1918, especially in the Kaiserschlacht offensive. At least 5,000 MP18.1 were built and used during World War I, based on observed serial number ranges of captured weapons. But it is possible that up to 10,000 were built for the war. Production was outlawed by the Treaty of Versailles, but manufacture was continued secretly into the early 1920s. Final production total ended at around 35,000.

Any ideas where those observed serial numbers are recorded?
