The second pair ( without the trim around the top ) look pretty good to me. They have a good shape to them and there should be some stamps on the inside around the top edge.

Original German Boots -in all their varieties- can be found on Germany's Ebay.de every day...might be worth a look...
I agree with Danmark! I like the second pair...
First pair look like Bergschue without the hardware. NH
