I believe it came in some, but not all E23, E24 and E28. Maybe late E12 as well
Trouble is, it was a temporary design. They went from the early design as seen on the E3/E9 to the new canister design with the slimer canister and the new filter type with a top bolt.
But a little later the cars got oil coolers and to attach those they changed the oil filter head again and went back to a lower bolt design, albeit with the slimmer canister and sometimes a drain screw as well. That design is an uprovement over the original top bolt design as well and preferable if you want to run an oil cooler but not quite as practical as the intermediary design which allows doing the whole filter change, more or less drip free (no hole in the bottom of the canister) from top.
The top bolt filter assembly is simple to spot on ebay though as it is the onlY M30 filter with: a top bolt
here´s one:

If you do find one and switch to it: let me save you some time:
Put the long bolt into the head before you mount it on the block. It doesn´t pass the intake manifold when you try to insert it after you´ve mounted the assembly!. Not a problem once installed as the bolt never has to come out again, enough to loosen it and take out the canister.
The perfect filter design is of course the later E34/E32 design, where the whole filter goes in from the top (as on practically every BMW since). But unfortunately that doesn´t work with the oil passages on our earlier M30 blocks.
