Stick Pin Grouping - WW1 - Identification Help?

[MAP]

Picked up these three stick pins today. They were all part of a single grouping that was brought into an antique store along with two versions of the same medal (see last photo).

As there was no name / provenance associated with them, the dealer was selling them separately. But we worked out a deal on all three. Personally, I feel they all belong to the same WW1 vet. I passed on the actual medals as they had no ribbons and one was missing the suspension ring. I think they were probably removed from a ribbon bar at one point in time as it still has some thread attached.

Can someone identify this black cross? I've looked and could not find anything. I know I have seen it but can't remember.

The first is a nice button hole 4 piece pin with and EK2, Hindenburg Cross, BWB and this ?? award.

The second is a basic EK2, Hindenburg Cross and BWB

The last is an EK2, Unknown and Hindenburg cross.

















This is the one I need an ID on.

That's the König-Ludwig-Kreuz. Have a look here:

Was betting which of you two would answer first!

Thanks to both!

Interesting that it would be an a bar that contained both an EK and a Wound badge if it was for "persons who had rendered domestic services for the war effort and who were not eligible for any other military or civilian decoration". Maybe he was wounded and then performed domestic services after being discharged?
