I'm saying that there appears 3 installations of bollards over time.So the picture you posted of the up turned bollard isn't from when CR was murdered? Are you saying that the steel bollards (pictured) weren't in situ at the time? Rather timber bollards were in their place?
1. pine log - the stump (125mm) with oil over it with (One bollard)
2. steel - 65mmx65mm at the time of the Corryn incident 2 side and a removable (it appears)
3. steel - todays installation of bollard 100mm x 100mm x 3
