Message Typer

A very ancient kind of machine which listens to short messages and transcribes them on small pieces of paper. The maximum it can type in one go is 100 words. since Moumin is syllabic it can use small stamps instead of a keys like what a typewriter uses.  The device is operated by a series of strings and levers which the person writing the message pulls and lifts in a sort of mechanical dance. Each string activates a specific stamp while the levers act as the enter and punctuation keys.

Utility

Creation of short messages such as telegrams.
