thank's for your suggestions, that gives me some hope ...... ! I only pray, the money of the DTM Berlin will be enough to try it one day ! Prof. Steinle wrote me, that their success in finding this kind of treasures is only round about at 8 % ...... It is true, there is something more to be found in the German lakes, so f.e. the FW 190 D9 salvaged out of the 'Schweriner See' (after 18 years still not completely restored !) was only found by accident, they were looking for another FW 190 D9 also of JG 26 lost the same day. This aircraft should still be there ...... For those interested in the progress of the already salvaged FW 190 D9 here a short link (in German only, i am sorry)
