As the 'barrel' in which the starting point for a Spitfire reconstruction is 'scraped' ever cleaner, I personally have no problems.
Several Spitfires now flying started with little more than a firewall, including three, PT462, MH367 & SM520, configured as new build two seaters. There are further such reconstructions in the pipeline.
In each and every case there is a clear 100% provenance trail back to an original RAF serial and identity. 'Thin but robust' provenance with total transparency has been the order of the day.
In the case of the two 'Turkish Delights' ML411 & MJ147, the latter reported to have been exported from the UK to the USA, there is no transparency.
Reported as recovered from Turkey about ten years ago, not one sighting or image has surfaced.
I would be the first to acknowledge and respect the right to privacy in these matters...however strategic appeals for parts and finance at various venues have bought these two 'Spitfires' very much in to the public domain.
With an ever thickening file of bile filled 'anonymous' hate mail to the world-wide Spitfire Glitterati, and forwarded on to me with concern, I am beginning to think I may have touched a raw nerve with this one.
