2 Karl Rosenbauer Nurnberg Germany clockwork boats  (NO KEYS) . Motor works on the one wound through the funnel - the other motor, which is wound through the stern, does not work and tabs are missing from the hull, however the deck can be made to click on with a little fiddling..  very similar boats are seen in a 1930 KRN catalogue as shown above. These appear like the first one in the catalog, without a rudder but with an identical deck to the two funnel versions.  Presumably therefore the eyelet at the back is to tie string in order to retrieve it as it cannot be made to return in a circle. Quite  rare boats in not bad condition. The other boat is almost identical but is not marked. Makes for an interesting display, with the top off one showing the curiosity of the different mechanism in the same hull.
