Gentlemen, can anyone advise me on this problem;

I have a Feuerschutzpolitzei short dress bayonet (please see pics) in good condition apart from two points, firstly some minor sharpening that I can live with.
The major issue is ; the blade is lose in the hilt. So viewed from the side there is approx 8mm of up/down movement at the blade tip pivoting from a point that appears to be about 10mm inside the hilt. My questions are;

1. Has anyone come across this problem before
2. Is the tang broken inside the hilt? I don’t know what the tang construction looks like
3. Is it repairable?

I have also posted this on the BCN discussion site.

Many thanks in anticipation for you’re time
