Glad you started this thread bobbibunny.
Have about half the clues, but don't know how to start populating the grid - thrown by the 2 x 9 cells to be populated. Presumably the 2 x 8 letter clues need to be modified and entered here?
Selection of what I'm pondering:
40. One local river's wavy (5)
17. Missing right rate Ruth's shed (3)
8. Military district outlaw reserve division (3)
39. German marks very practically making a comeback as sum's dodgy without (7) - have UMLAUTS - but can't work out middle section and if a letters missing
35. Taking the tops off the deal pencils, that's pointless (4)
36. Eilidh's stripping wearing about little to begin with (7)
Any hints appreciated
