There was still some doubt whether
Cuckoo had a British antenna, but I think I've found conclusive proof:
That pointed thing is not a normal fitting on Panther turrets, but does match the conical shape of the 'A' aerial base for the British No. 19 set. Holding my turret in front of the screen in such a way that it covers the turret in the film of
Cuckoo as closely as possible, the aerial base I glued to the Nahverteidigungswaffe lines up almost exactly with the one in the film footage, so I feel confident in saying I probably got that bit right
I noticed this when going back and forth through that footage to try and work out what stuff is tied onto the right-hand side of the tank. I made some progress with that stowage but I'm not there yet:

On the left, I added a second shovel (from the Tamiya set of British infantry on the move) and an axe (from a Sherman kit) because they're visible in the photo of
Cuckoo driving down the forest road. That picture also shows the handle of something halfway down the left-hand side of the hull, and though I can't make out what it is, it was probably held in the rear clasp intended for the crowbar that sat above the tube for the gun cleaning rods (which was missing on
Cuckoo). I decided to add the hammer from the kit, glued around a tool clasp from the crowbar, because it's plausible and sticks forward approximately far enough.
On the right, I converted a shovel I found in my 1:35 tools spares into something that can pass for a common Dutch shovel and glued it into the tool rack.
