Kriegsmarine UBoat badge help

Hello

Asking your opinion about this badge . Is the hinge system usual for BHM ?

Thanks

PS sorry for the bad pics

The badge generally looks OK, but the pin set up isn't the normal one. The retaining clip also looks like a repair job. This one has the L/18 mark on the back of the badge, not the pin, but the pin is typical of what you'd find on a zink L/18 (the Tombak ones are different).
