Flakkampfabzeichen der Luftwaffe - unmarked ball hinge

[KatManDude]

Hello...I have had this badge for awhile and feel that it is legit but would like to run it by the more knowledgeable for opinions....the eagle details, gun details, hinge are similar to one I've seen posted by rbminis(thanks!)....the back is slightly concave behind the eagle on gun on the reverse as well....the hardware is slightly different though....

is is legit ?...maker attributed or the infamous unknown ball-hinge ?.....thanks in advance for your input

Yes, it looks like an unknown maker, ball hinge to me.

Nice patina on it, agree with the unknown maker.

thanks for the confirmation.....another question, is the eagle a different type of metal on these ?.....the finish has held up(whats left of it) better on the eagle than the wreath and gun....
