Yes, but first of all we have take into consideration all options.
For us above mentioned option is one of moust imortant.
So please try to help us.
So we would like to ask about contact with person which could have Flugbuch of Hans Bock. or all pilots JG3 from Prenzlau.
Yes we know it can be not possible after so long time but .... .

We think that somebody could find during IIWW fresh wrack after as it was crashed and also pilot's Soldbuch and rewrite on the small piece of wrack pilot name "Bock".
But it is only one of options.
We almost sure come back to this place and we will search engine from wrack maybe it help us to find serial number of engine.
