The German's got very nasty with booby trapped fuzes which can still be functional today so they do have to be exceedingly careful with Luftwaffe bombs. Although being German they had a habit of being German and labelling everything very clearly which can help.
I can’t see there being a lot of volunteers eager to peer closely at the writing on the various parts of the bomb. Particularly if they have to clean the rust off first. Still, it could have been a Swedish bomb with instructions provided by IKEA.
