hi rhino , i worked on beam trawlers for about 8 years and without proper name and number it will be impossible to tell what its supposed to be.
Its not all bad news as by what i'm seeing in the picture i would say its dutch and is trying to be a 40 m long by 8 m class of beamtrawler.
I say this due to been an old type hull with a covered in stern , and square wheelhouse.
You will have to do a lot of research on this boat as a lot of the details are wrong or missing , to give you an example the derrick ( upright black poles in the middle ) stays would never be chain because you can not tell when its to worn, but instead they use wire.
the other good news is there is lots of information out there , start by searching for beamtrawlers for sale on the net as this may bring up a boat of simular type and age to work from - and the added bonus of pictures.
best of luck with your project
