Hi everyone, I'm a newbi on here looking for any information on the above. Essentially I'm researching my Grandfather's service history, the information sent to me by the RAF details a temporary posting to 5152 Squadron in what looks like May 1943, however, I am finding it very difficult to obtain any information on the squadron or unit. The best I have managed to do is information on a Mobile Signal Unit of either 83 or 85 group who were involved in the Normandy landings, this was 5153... One out.lol My research suggests 5152 is a sub unit rather than a squadron as identified in the service record, I've approached the RAF Signal Museum, assuming 5152 could be another MSU, but they said they held very little information on the various units. Any information, suggestions, etc. Would be greatly appreciated. Thanks, Mark.
