CuriousMarc inspects a newly arrived Teletype Model 19, an early military unit built around a Model 15 keyboard and printer, after an initial rough cleaning. It is the first part of a restoration series and touches on 5-bit Baudot code.
HN commenters point to this restoration series as a thorough explanation of how teletypes work at every level.

CuriousMarc, a volunteer at the Computer History Museum, recently finished a video series restoring two Model 19 teletypes into working order. It's a long series but eventually explains how the devices work at all levels, and shows off some of the more niche features of the ttys. Well worth the watch. this video
I was staggered by how much adjustment was required when watching CuriousMarc's excellent Model 19 restoration series, seems incredibly finicky. this video
He has this playlist on the same channel where they restore the Model 19, and they explain in detail how the decoder works: this video
