Bring it back why?
It looks very impressive in it’s current setting and is cared for by the local people.
If it is all brought back it will look like a pile of scrap and if there is no funding in place to display and re-assemble it on a framework (10,000 sq. ft. ideally indoors!) then it might be seen and appreciated by fewer people than enjoy it now.
The locals I’ve spoke to are worried that it isn’t being cared for and that since being on a prominent TV documentary has been raided pretty badly. Canopy frame, turret frame, and numerous other parts have gone with many ending up on ebay.
Given that theres no legal protection of NF920 a recovery of what is the last 617 Sqn Lancaster seems the sensible option to preserve all or some of what remains.
