But to try and sell such a block with the current order book makes no sense!

Unless it is to block, which this has the look of.

If you wanted to sell such a block it would make sense to break it down, so as not to appear so big, putting off potential buyers, IMO.

Sadly at the current SP it doesn't equate to much in $ value terms, further reinforcing my opinion that this is a block, rather than someone looking to offload.

It sure looks like a block to me!
