Various Shelf Brackets see photo (Harborne B32)

Hi all, these are various shelf brackets that have accumulated on my garage shelves over the years so could probably do with a wipe over. The top four and one odd one in the photo are the kind where you screw the back piece to the wall and then the other part slides down into it which hides the screws.
The other two are just the normal screw to the wall type. Kind regards Eric
