I collected German militaria for many years, and I have a few red flags on these pieces. First, the eagle just doesn't quite feel right when I look at it under magnification. Something about the embroidery seems off to me. I would suggest putting it under a blacklight to see if the white thread glows. If it does it's a reproduction. Not glowing doesn't mean it's definitely real though, there are very good fakes that use non UV thread.
The SS tab.....I have seen that exact same label on many reproductions and fakes, particularly coming out of China and former Soviet countries like Poland. Here's a genuine label,
The infantry assault badge..... I've never seen an original with the pin riveted like that, also it looks to be cast from a mold rather than stamped as an original like that would have been.
The Panzer Badge also seems a bit weak on detail, but actually looks fairly good. There's no makers mark, but that's not really a problem as some were unmarked. I still kind of lean toward it being a repro, but it's a piece I'd need to have in my hand for a good opinion.
The ribbon bar...... The back is one I've not seen on original period pieces. Many were hand sewn on the back and show stitching, or were covered with felt. Also the shape is wrong, the length of that particular one is more what I would expect from a Luftwaffe ribbon, but that's not a Luftwaffe emblem, it's a police emblem. These ribbon bars are being reproduced and I know of at least one dealer who sells them to re-enactors. Here's a photo of the front and back of an original mounted with other ribbons....

I really have doubts on the authenticity of these pieces based on the pics I'm seeing. You may want to get a secont opinion from the folks at
Wehrmacht-Awards.com I sold off my collection some years ago, and I'm not up on all the latest research on these items, so my opinion is based on my experiences several years ago.
