Well,i cannot comment on the Heer Flak badge or the SA badge,but the High Seas Fleet badge is a fake IMO based on the zinc Steinhauer & Luck badge,sorry to say.
The images are not that great but the pitting on the reverse suggests a cast fake to me.
Here is an original variant of this type by S&L with the folded sheet metal hinge and needle pin.
The badge shown above definately lacks the crispness and detail as seen on the original,as we can see.
Very poor photos to judge by but I don't see any problems with the SA sports badge. I believe the Heer Flak is a "lizardman" fake.
