This would need to be a non op feed. A new one on me. Please enlighten me if you will.
There has always been rumour that the TSF could/and would be used in earnest but when push came to shove spares and cost made this impracticable.
Personally I can see the old girl having the legs cut off and being sold for scrap. The new TSF being at one of our sites further north utilising an existing set into a dummy load.
Time will tell but they need to get there sh*t together.
