Gunter Phrommer, I may have his last name messed up, but google Dutchman wood works. I think.
Just glue the ebony back in place. If you are able to get the front wood off (not tough, two screws on that one, I think) you can work the ebony free, clean it up with 320 sand paper on the glue surfaces, glue it up and wrap surgical tubing, stem to stern to clamp it in place.
Done it about a dozen times.
Good luck.
Best,
Ted
Dutchman Woodworks is Larry Schuknecht. He does reproduction butt plates. He’s in upstate NY. Good dude and a pretty good gunsmith/stockmaker too.
