Ok after storm last night had a small leak at the top of our window in the kitchen. Took a look above and lifted off coping.
Seems the lead stops short of the cavity and there is no tray or dpm across the cavity :( When i lifted the stones the cement bed on inner wall was very wet which looks like its been leaking in here and running down the inside of the inner cavity wall.

How can i fix this till i get it all relayed properly come spring? Any suggestions do i lay some dpm over or under that lead across cavity? Any suggestions appreciated thanks.

From your post and pic its difficult to understand what you mean.
Can you show a larger context pics from outside and a pic from inside?
What is the lead you refer to?
How have the copings been fixed?
 
Ok will try and get another photo, dark here now but i think i took another angle.
In the meantime if you click on that thumbnail above should give larger view? Lead flashing on right hand course only which literally rests on block work with mortar on top between coping and lead. You can see at the top of the photo a coping stone (single weathered sloping towards inner drain gulley internal wall) they are bedded on mortar directly on top of block work.

The leaking side seems to be the right hand course, in more detail, the face between the lead and mortar, and coping stone and mortar, sort of both faces. I could lift the blocks off and the mortar off the lead, so none of it bonded well.

No DPM between cavity or zinc/lead capping evident currently under blocks.

I'm not much wiser. Why not take the pics in daylight?
