Contact BD to find out what's compatible. Their Der. Hanger page has a list by mfg.

It doesn't list the Steel Corvus by name, but it may be compatible with the available offerings. It's probably either the Zonal Al or the 7k series.

People hardly ever post pictures of their BD bikes, let alone a derailleur hanger.

Best bet is probably to wait for BD's response about the appropriate der. hanger and then get a couple to have a spare.
