Further to WO 344 - Prisoner of War liberation questionnaires.
Just noticed that Lee Richards at @RCRE www.arcre.com provides a UK National Archives WO 344 service, noted in these terms:
"When ordering a copy of a liberation questionnaire, there is a 50-50 chance that the requested prisoner of war never completed a questionnaire. In the past, when this happened, I did not charge for my time searching for the questionnaire. This has proved unsustainable. Therefore, in future all questionnaires with the first initial and last name of the prisoner of war will be copied from the relevant document and will be charged on this basis. In most cases, the minimum charge of £6 will likely apply but could be higher for very common last names. The charge still applies even if a questionnaire for the POW is not found."
Cannot say what level of Ancestry monthly membership is required (from roughly $A22 to $A60) to access WO344 records.
Up to individuals compare costs, depending on no of PoW qs being sought.
Lee's service has been consistently prompt and affordable in all the years of my ordering though @RCRE.
