Luftwaffe Erdkampfabzeichen authentication

The attached images show a badge which I am considering buying.
To my inexpert eye it appears to be a good Osang LW Erdkampfabzeichen, but I'd greatly appreciate the opinions of more experienced eyes !
Thanks in advance.

Not my field of study, but the badge looks okay to me.
I just don't know it they produced them unmarked.
The only examples I could find were all maker marked.
Wait for other opinions.

I don't recall seeing one without a maker either.... here is my Osang example as a comparison...

(and a couple of photos from the internet of another Osang).

This is not an award I know much about but using Previttera's Luft Combat award book as a reference, it only mentions two variation, both of which are maker marked.

I tried to compare this award with the one in his book. But these photos are just a bit too blurry, especially on some the the key features. A close up of the rear rivet might help too.

Lastly, the reverse of this award seems to have casting flaws to the left and right of the rivet. And does not appear to have any hand finishing.

Thanks for the feedback. Too many question marks !
