It's been so long ( circa 1978 ) since I cracked a technical book on teletypes ( I was into shortwave listening back then, and intercepting radioteletype (RTTY) feeds ) that the exact relation to baud rates, character per second, etc., is hazy, but standard speeds were 60, 66, 75, and 100 words-per-minute ( WPM ). That assumed some arbitrary average word length, and was based on a 5-bit character, which was standard teletype practice.
The baud rate is related, and numerically close to WPM, but not exactly the same thing.
60 WPM was the old US standard, 66 WPM was European, and 100 WPM was used by the armed forces a lot... I actually had a surplus Kleinscmidt portable tty that had change gears for all speeds- it came in a neat magnesium, watertight carrying case. Kind of wish I'd held on to the dern thing, now!
LOL
Small world. I had a Kleinscmidt too. Now that you mention it, I remember changing the gears in it. (Very easy to do)
I got mine about '69-70. Somewhere about that time. I had it hooked up for RTTY also. (Receive only. I had not renewed my ham ticket, never did actually, got too busy with other stuff) It was fun.
