Let me first state I know which document you are looking for, but I do not have it myself.
But not too long ago I started to do some climb tests with bombers. Unfortunately, due to lack of time it's not finished yet, but there is already a lot of data.
I had recorded time to climb from sea level to 5k-30K for the various AH level bombers in different configurations (ordnance/fuel). What I didn't note were the horizontal distances covered, but with a little experience that's easy to guesstimate from the time spent. All times are rounded to the closest full minute, fuel endurance is given for sea level only (can improve significantly depending on altitude). Fuel Burn is 2.0

Maybe later this year I have the time to finish my AH bomber handbook (of which this time to climb would be only a small part)
