A great read.  The photo makes it clear that morse and RTTY coexisted, which is pretty obvious to me as morse was an established standard long before RTTY and so RTTY must have been phased in.  Technological changes like this can take decades.  The fact that something is an established standard can keep it in use long after it is technologically obsolete.

I love the description in the text of the improvised paper-tape drying oven that was needed because damp paper tape doesn't work.
