Edit: Oh wait nvm, I had one left - so nommed!
Once again, congratulations for this very nice quiz! Nominated, of course.

The vast majority were fine, but postbox/letterbox and padlock should be added I suggest - it's much harder when you have to stop halfway and think what an alternative name might be!

Nope doesn't work for me either!
I'm terrible at remembering visual details but good at remembering sounds and concepts.
