No. 1667 Heavy Conversion Unit's ORB in AIR 29/614 at The National Archives in Kew ends in February 1944, while the unit was still in existence.

I'm interested in two crews (at least) who eventually came down in my research area, and I was keen to have a look in the HCU ORB to see if they were mentioned in it. They went through it around May 1944.

Does any forumite who was confronted to this same problem can point me to an alternative reference ? Station ORB may be ?

Thanks in advance
