ORB's for 17 OTU, 5 LFS, 1661 HCU

[Johnnie]

Hi.

I was just wondering if OTU's, HCU's, and LFS's had ORBS or
something similar that would note where an individual was posted
once he had finished his course and moved to an operational unit.

I am interested in a Navigator (D. H. Aldridge 1577453) who was at
47 Air School (Queenstown) from August 43 (ish - No. 6 Course).

He then moved to 225Air Navigators Course at 1 (O) AFU Wigton
in April/May 1944, before moving to 17 OTU in June 1944 where
he stayed until mid July (No. 85 Course).

In August he appears to be at 1661 CU on Stirlings until he finally
moved to No. 5 Lancaster Finishing School sometime in October 1944.

While at the OTU, HCU, and the LFS he flew with F/S Cambell, so
I assume he was his regular pilot who he crewed up with.

Any adivce would be great.
