I'm sure they are all out there somewhere but keep one important thing in mind. They were all written for the old bass setup and the tech that went with it. Gut G and D, gut wound on A & E. Because of the much wider oscillation and to avoid the dreaded 'buzz' on the fingerboard, the nut and bridge were much higher than today's setup. Also, all 4 fingers in blocking down the string was the way to go. Block fingering, high action all caused physical and musical problems. So, don't take all those excerpts as gospel. Think outside the 1,2,4 box on occasion.

Been there, done that.....
...well just because Zimmerman's fingerings apply, as you would say, to an outdated and technically inferior bass set up doesn't in any way reduce the value of these books. I think part of what Zimmerman did here was preserve for future generations the traditions of bass playing as taught by Anton Torrello - although I can't speak from experience, as I am to young to have studied with Zimmerman himself. The Bowings, supposedly those used in the Philadelphia Orchestra, and fingerings, albeit simple - gravitating to the lowest positions practical, are clues we can use to understand a sound and approach to phrasing music that was taught then.
Of course that doesn't invalidate any points in your comment... those fingerings, in light of the current state of bass playing, are often too old fashioned to be practical. But wait... who plays every single suggested fingering in every piece of edited music anyway!? I'm sure any student tackling the 9 Beethoven symphonies has at least some basic understanding of how to come to his own fingerings, picking and choosing from suggestions and thinking for themselves.
Looking beyond Zimmerman, Warren Benfield, in his book, the art of double bass playing related an anecdote about Anton Torello -
The late Anton Torello, principal bass under Stokowski and Ormandy and teacher at Curtis, once said that when he was a student in Barcelona (his whole family were bass players) he wasn’t given anything to eat until he knew his lesson. Sometimes he got very hungry. What he would do to learn etudes was to develop his fingerings. He would work out as many ways as possible to play a passage and learn them all. Then he would put his music away for a day or two, and when he tried all the fingerings again, one was usually clearly better than the others. (pg 24)
While the end result may seem dogmatic or archaic from a modern bass playing perspective. The idea of finding a fingering that fits the player, fits the music, and sounds good wasn't just thought up in the last 20 years.
Sorry for being a bit long winded, I don't intend to contradict anything you said - and I do recognize the practicality, as a teacher, of warning against taking the printed fingerings dogmatically. I just thought to remind that Zimmerman's contribution contains many positive points to consider - not only the limitation of old fashion fingerings.
