understand what your saying Alpha,but the amount of money it takes to get certain airframes back into the air ,like the recent mossie etc im sure it would be a fraction of the re-build cost as its already there.I have no knowledge of these things apart fro a love of seeing these this fly.Im sure there would be probs with an "airframe"over 60 yrs of age taking to the skies etc but imagine it!!!
I personally would love nothing more to see a Tiffie or Tempest take to the skies

never gonna happen
