A rough milled cut (maybe one for a paint job?) ,but shows the 'captured button' type primer used in the 105 and many more large artillery shells.
These primers often look like they haven't been fired, as can be seen these little floating buttons are thick enough (5mm) not to dent!
The "captured button" primer as you have sectioned is an added safety design used in the U.S. to accomodate the extreme pressures of the large bore propellant chambers. During this past Summer, a private owner of an artillery piece here in the States was firing his 76mm tank gun. His reloads did not use the isolated "captured button" design. He was using standard .50 BMG primers. The high pressures incurred during firing blew the primer back into the firing mechanism, seriously damaging the firing mechanism.
