Lanterns on concrete brackets

This is a Philips MI26, and a Thorn Beta 5 (Mk.15) on their Stanton 10F concrete brackets just after they were removed. The old columns had defects on them, so thy needed to be replaced. But the brackets were good. The MI26 bracket came off the top of the column easy, but the B5 one needed a bit of persuasion.
The B5 is likely the original lantern to the bracket and column, the MI is a spot replacement.
