Bill,
BENGLOEs movements are held at Kew in piece
BT 389/4/80
The file can be downloaded for £3.50. Appears ok to me although I haven't gone beyond looking it up.
Did they not also send you an email with the file reference. If so can you send it to me and I will take a look. It will not have anything to do with the cyber attack.
Regards
Hugh
