Digging for history

The garden behind our office has been neglected of late. So, yesterday was spent digging weeds. Then, last night, someone commented on an old Facebook post about objects that were found in the garden as it was being reclaimed. See if you can guess what all these things are, and don't cheat by searching the Facebook archives!

The shell timer to the left was also found in the garden. There was a machine gun set up by the Americans behind this house, guarding the road into the town.

The timer on the right was found in Meautis, scene of massive battles between the German 17th SS and the American 83rd Infantry Division. Obviously, this second one has been cleaned up. The craftsmanship is striking, especially when you think that this is something made to be destroyed.
