Need help IDing two German helmets, Post-WW1 Pre-WW2 May,2012

My mom's boyfriend had these in his garage, war-time bring homes from his Uncle during WW2. The leather helmet appears to be from after WW1 and before WW2, it is also quite tiny so I think it is some sort of youth parade helmet.

The Metal helmet I am pretty sure is some sort of civilian corps, given the name under the helmet. Some sort of air protection thing, it's mostly the second leather helmet that I have no idea what it is... Attached Thumbnails

ID Vehicle (Carden Loyd MkIV???) May,2012

Correct me if I am wrong but the vehicle at 0:22 in this video is a Carden Loyd MkIV?

If so, I take that it is used as a light SP Artillery piece?

Says it uses a new lightweight ammunition. I am a bit hesitant about what exactly that is, I guess I'll have to wait and see.


Anyone got any more info on this?
