If you take a look at Nashorn pictures, most of them don't have the rain guard around the radio operators hatch. You could leave it off and still be accurate.

The part from Dragon is very stiff and if you try to anneal it, it melts away! Best to either replace it with sheet plastic or not use it at all.

Hi, looking at the instructions I would say that it is meant to attach to the plate, so that it surrounds the opening. Presumably the intention was that it stops water dripping off the sloping plate through the hatch when it is opened; if it was attached to the hatch itself, it wouldn't do that. The vertical blue arrow seems to confirm that in that it is pointing to the plate, not the hatch.

It's one of my least favourite things - a piece of PE that attaches edge on with nothing to locate it. Like sticking a piece of paper edge on to another piece.

Personally I'd ignore it unless you get it fixed on right first time.

This photo makes it look like it was never there as there's no trace of it, although there is a big hole in the deck not too far away which might have ripped it away...
