Some RF rounds

Dug a couple out for viewing and ID'ing from those that may know of interest Rt to Left the rather small round, 4th a rimless rim fire!, a Flobert round! the.22 RF is on the left as a scale.
Some of my .22 RF rounds are copper cased which I find rather unusual also I have pictured the rimless H/S and the rather diminutive rounds H/S as well. TIA

Are you sure that the "rimless rimfire" isn't an internal centerfire cartridge?

3rd pic post 1 is a Sellier and Bellot headstamp?

Thanks Jim I did not put it the right way the eyes ol bean bit ancient anyway it is a rimless round and quite the novelty it does have a cannular on the case base wonder how it works!
