Many thanks, Alertken and Doughnut.
I suspect that ‘Impressments Log’ will prove to be, like certain other old and small print run monographs, impossible to obtain on the secondhand market! The sort of publication that is jealosly guarded by those who have it and, on the rare occasion that one appears on the market, is fought over by potential purchasers and eventually changes hands for a tidy sum! That being said, does it go beyond just identifying those aircraft impressed – type, civil registration, military serial, impressment date and date of restoration to a civil register – and extend to all or any of the particular information I am seeking? If, Alertken, you can let me know by reference to your 1959 edition, I shall be grateful.
I have, I think, identified all aircraft that were impressed and returned to the UK civil register. However, Doughnut, where do I go from there? The RAF Museum tells me that it has no information relating to this particular area of interest to me. Using all the keywords of which I could think for the purpose of an online search, I also drew a blank with the National Archives at Kew. So have you or anyone else out there got any ideas that might help me!
