I think the HJ Achievement badge is ok. If I am not mistaken the letter 'B' means it is a replacement badge

i dont like the SA sports badge due to pin and hinge presentation,,also the front looks odd to me,...
Thak you guys for your points!
You have confirmed my own guess that SA sport badge is the bad one (typically fake pin / hinge) and the HJ badge is Ok.
I have never seen that type of pin on an original either. Good to know where these have come from.
