Help identifying centre caps

Lads have these two caps in my box of parts and they are reasonable good condition bar the roundels.

Any idea what style wheel they are from?

The BBS one is metal and twists to lock.

The second one is plastic one-piece, the part number in realoem comes back as being applicable to E24 E32 E34 I think.

Are they style 5 variants?

Looks like it will fit style 5's

Nearly sure there for E34 15'' Style 5.

The twist lock one was from an e30 OEM BBS wheel, as above with the other it's from the early style 5's
