Support needed with oilpan identification

[Clubsport_CSi]

Gentlemen,

I would be very thankful for your expert support on identifying the M30 oilpan / sump displayed below.
Does someone know of other similar oilpans and where they were used?
I will be happy to tell you with which parts it came and share the little knowledge I have about the parts, but do not want to bias the discussion from the beginning.

Thanks a lot for any helpful comments in advance!
Kind regards, Dan

Obviously not a match, but perhaps good for reference. Notation reads "e21 333i"

Woha - is that the Dietel 333i E21? Do you have details on that car?

 

[Clubsport_CSi]

Have any of the E9 motorsport specialists seen something similar?

scan of only remaining pictures - pretty much everything before 1992 was lost in Hurricane Andrew.

What a pity that this car has been lost! My condolences...
I am not so much a fan of the body kit and rims, but I love the engine swap and other modifications to the car.

Maybe a picture of the oil pump that came with the oilpan triggers something:

Alright, not much direct feedback but with the support of a very friendly expert here on the forums I have been able to verify from a second source that the pump is very likely a genuine example of the homologated 3 stage drysump pump in Alpina version, so externally mounted on the exhaust side of the engine. I also got the mounting parts.
Photos from today, parts are wrapped for storage currently.

Also got the lines and tanks.
So, I just still wonder how this fits with the oilpan, as it is definitely not like the works pan and does not look like any drysump pan I know. More like the oilpans with increased oil volume and internally mounted pump...
Also during the semi-dry period they used internally mounted pumps as far as I know. And I never saw a picture of the semi-dry pans anywhere...
And the pan clearly has the fittings for the oil lines.

Cheers, Dan

Dan, i have zero knowledge, but as you state that the sump was part of a homologated package, it means it must be documented between bmw and the FIA.
That said, it'll be hard to get your hands on a copy, as you're likely not Bmw or FIA employed either.
