Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"
I once got told that Darren drums used to be used for transporting pig sperm before being then sold on to the caving community? Was this just a pub / club hut story or tru?
Thanks
These drums are from general chemical/industrial transportation origin.
The original company who "invented" them is CurTec, I think from the Netherlands...
