238 Squadron Battle of Britain pilot logbooks

According to my web search results, there are some online sources that might have the logbooks you are looking for. One of them is the RAF Museum, see https://www.rafmuseum.org.uk/research/default/archive-collection/aircre… suika game, which has an extensive collection of aircrew logbooks, covering all aircrew trades, periods and theaters, although the majority are from the two World Wars.

Another source is http://forum.12oclockhigh.net/archive/index.php?t-17129.html , where there is a thread about RAF and RAAF pilot’s logbooks on the net.
