I think that you've all had enough of this one.
I compiled many pages of description relating to airfields, unit codes, aircraft flown, and key dates of changes.
When I tried to insert it all into my Museum notes, the formatting went crazy. It looks like it will be a while till I get that sorted.
Meanwhile, I have uploaded a page with just the Lancaster tail markings.
The Halifax tail fin represents an aircraft from 4 Group, 158 Squadron
To find the Lancaster identification, click on the link in my signature, select the Flying Visit Museum, then select Special Detail followed by Bomber Command.
Thanks to those who tried.
