Forgot to mention, some Teletype machines were configured to both CR and LF on CR, to prevent overprinting.

Actually, this is one area where I can speak with a lot of authority. When I started in the telecom industry, 46 years and 8 days ago, I
Congratulations on a long and I'll bet, storied career.

left side. By having the LF after the CR, extra time was provided. Many people also got into the habit of CR LF LTRS (on 5 level Baudot machines) to provide even more time and ensure the printer was in a known state re letters or figures shift. In fact, one of my first tasks, after completing my training, was to go to customer sites and replace the answer back drums (used to ID the machine) on Telex
I'm curious now, an answer back drum? Like a single spinning drum whos only task was to provide an ID/handshake signal? I only ever fooled around with a telex in the radio shack at VE3OSC and all they'd let me touch was the keyboard. :-)
machines, that had LF CR, as those would cause problems on overseas connections. The standard on those drums was CR LF <Customer ID> CR LF LTRS.
LTRS = long term return signal/state? like HELO OLEH?
Bottom line, it was always CR LF back then and that followed to any computer that used a Teletype machine for a console. However, on computers, a CR was generally used to denote new line and the

added the LF.
In industry, timing's are everything. Leveraging a mechanical advantage is as old as the oldest timepiece itself. It would make sense to me that the engineering of the day might take advantage of the mass in motion of a plattens own return movement, in order to advance the roll a notch or three on a sudden stop. I use to see those types of timing geegaws in manufacturing and industry all the time.
