for later se productions, the olives starts to have little dots on back of them( 1dot indicates small 2 for medium 3 for large)and it is this kind of olives own a smaller inside that could be perfectly installed on um2 not causing any sort of loose.
also i found the new olive not expand as good as the early ones
