Here we have a Seefahrt 1st Not (Shipping is Necessary) tinnie from 1935.
This pieces were constructed by being die struck and made with an aluminium base, then silver washed and lacquered.
The front depicts a sailing ship breaking the waves, below an NSDAP national  eagle (clutching a wreathed swastika). On the outsides of the badge it reads “Tag Der Deutschen Seefahr 25, 26, 5 1935” (day of the seafarers). on the reverse we have a horizontal tombak pin and a makers mark. The pin is in good working order.

Great little item in very nice condition.
