Lifesaving?? Medal Help

[flatlander]

This Pin was given to me years ago, kind of resenbles a tinnie but looks to be silver or silver plated. It's marked REICHSVERBAND d. Jnhaberd. RETTUNGSMEDAILLE FUR RETTUNG AUS GEFAHR. There is a marking on the reverse of the pin , on the eagles head but I can't make it out. I think it has something to do with lifesaving, hopefully someone more knowledgeable can help me out. Thanks in advance.

Neat membership badge of someone in the Association of awardees of the life saving medal.
I have their directory from 1940 : about 60% of people in Germany who owned the medal belonged to the association in the 1930s.

i think it still exists.
