Ooops!

Dropped it, onto tarmac too. I thought that would lead to sad times but, fortunately, it still works but it has to be slightly undressed to do so, see the extra.

There's a little spring come off that shuts the bottom lens shutter cover, which is why it isn't closed properly. The spring is about 5mm long! Amazingly it was still inside the cover and I just need to find a way of reattaching it as it is super fiddly. 

I will prevail!
