RS30 asked;
I see a Belfast is still operational. I wonder whether it could be the alternate engine test bed airframe?
As well as the operational Belslow in Oz there's another parked at Southend (G-BEPS) which until recently was being considered for return to service by Heavylift Oz.

Work then stopped whilst they tried to find another prop. At that time I wondered if it was maybe being considered as a TP400 testbed. Eventually, a fourth prop was located, the aircraft was washed and a team arrived from Oz to bring it back to airworthiness but after several more weeks work the effort was abandoned earlier this year, possibly due to certification issues? I believe it has now been stripped of useful parts and is likely to be scrapped very soon (if it hasn't already been scrapped).
I wonder whether the Belslow would have been a practical testbed for the TP400? It would certainly give the engine a lot more weight and drag to work with. The extra power wouldn't have done the Belslow any harm (assuming it didn't pull the wings off) - might even have turned it into a Belfast, especially if they eventually fitted four of the TP400s
