My friend from Germany had another thought...

 

dear marion

here is a comment to the other photo on the website. it appearce to me as a base plate of a mortar,however i can not identify its origin. there was an american motar with a caliber of 81 mmm during ww II but it looked a little differnt to me since the photo is also very blur its hard to determine. more heidelberg photos to come

cheers
