It's a very long time since 05 was used for take-off and that runway was very rarely used - never as much as 23. I did some 05 ops in the early 70s during a snow storm, both landings and take-offs!! 23 was used for take-offs frequently when there were strong SW winds. During one spell of southwesterlies I did 23 single-runway several times, with a few deps off 27R at the same time. Great fun.
