Kriegsmarine Diver Lifting Bag--help needed!

[HxC]

hello all, I have this piece in my collection; it was said to be a german ww2 buoy. it wears some markings, but i can no longer read them as they fainted out because of age. It's in quite good condition and measures around 1 m / 70 cm. any help would be most appreciated. greetings, Matthias

Is this supposed to be some sort of a marker buoy?

This is a divers lifting bag, you can lift stuf frome the sea, the diver can fill the bag with air to lift stuf frome the sea bed.

Any idea about its origin sir? Is this military? Greetings,matthias
