Hi eskiserkan
I am currently building a Dusseldorf. The hull and cabin both required trimming & sanding of the edges, otherwise they are well-finished.
A lot of parts are die-cut in either ply or various thicknesses of plastcard-like sheet. Many wooden parts are quite difficult to cut out (no, you cannot just press them out) and all require finishing. Many (most?) parts have to be fabricated from brass rod/tube, ABS or wood supplied.
Also remember that there are 2 kits of extras to make the various features work - all adds to the cost. I will not make the dinghy rise & fall nor the crane rotate. Similarly I shall leave the anchor winch non-working. I do not think these are worth the effort. The monitors will be fully functional though!
All in all a nice kit with plenty of detail if you are not in a hurry. Hope you go ahead and purchase.
Apart from the Robbe website, the only picture (very small) I have found is on the Model Fireboats website:
