Time for a clue:

This air complex consisted both of a water and a land drome. Here is the land side a few years later.

The water drome no longer exists, but the land aerodrome does and is still active.

Although this location isn't in the UK, there is a British (non Empire) connection linked to the first picture.

Hope these help.

Is it connected to one of those altruistic military interferences entered upon by the brits around the end of WWI ? "North Russia" perhaps ? LFH

Kasumigaura Naval Air Station

Kasumigaura Naval Air Station it is - sabredog has it.

The British connection was the British Air Mission in 1922 - the lakeshore drome was in the process of still being built as can be seen in the 1st image.

This is a later image - a complete change. The "road" on the left leads to the land aerodrome.

Apologies for the delay;
Open House

I hope this place has not been done.
 

Complete guess, Woodford?

'866

Nope - kind of a strange one all those lancs are a little misleading but they are either "going to or coming back from" not sure which. I hope that is a vague enough clue.

Victory Aircraft Company (Avro Canada),Malton Airport,Ont ?

Well you're on the right side of the ocean!:ok:

Would it be in Alberta

East of Ontario.

Could be Dorval ? OH if correct. LFH

continue further east but it is not on an island.

RCAF STATION PENNFIELD RIDGE,NS?

Greenwood, Nova Scotia ? And if correct, are the Lancasters for Tiger Force ?

Not Greenwood but you are getting closer.
Not sure if they are for "Tiger Force" but that would be my guess also.

Thought I had one, but no good! Still looking...try this one, bit of a long shot as the hangar layout does not look right, RCAF Dartmouth NS? Nice challenge, I knew nothing of "Tiger Force" until now.

'866

Not sure if this ties in with the geographical clues, RCAF Lachine, Quebec.

Yer close but in the wrong province.
