Hi Armystuff,
TonyE has pretty much answered your question here, I agree with him on the possible id of the small round and the rolled brass case but as mentioned it would be easier to pin it down with some measurments. The small round can really only be the 2.7mm Kolibri Auto or the 3mm Kolibri as the next rebated rimless round of this sort of size is the 4.25mm Liliput Auto and it does not look that big.
The 2.7mm Kolibri Auto is a now long obsolete round and a collectable one although i am not able to tell you it's value it wont be a huge amount. As a point of interest the weight of the bullet is only 3 grains compared to that of 55 grains for the modern NATO 5.56mm bullet. And according to a reliable source only developed a whopping 3 foot pounds of muzzle energy.
As for the larger brass case i am looking into that one as TonyE said there are a fair few rounds that are similar to that.
Hope this is usefull,
Weasel.
