[Segmund Tang]

Here are some luftwaffe trade badges of my collection. Though they are not rare and not expensive, I can not be sure of their authentity. Can some one help me?

Thanks!!

Tang,

Pictures of the back side of each would help and detailed, close up shot of the top two trade patches would also be nice. Thank you. Steve

Tang,
You bought these from me off Ebay. They are extras from my collection. I can assure you they are good period pieces. If you have any doubts I will happily refund your funds to you.

Authenticity

I have seen these badges personally, as I have visited and handled Garth's collection on countless occasions. He has collected these for years.

If you got them from Garth, you have nothing to worry about. He is the Detlev of Insignia.

Sorry Garth, I am not intended to offend you, I just want to be sure about them. I considered them as original, otherwise I will not buy them. Sorry again. I hope you can understand and forgive me!
