Many thanks, everybody.
This looks simply stunning Przemo! Is the kit really so good as they say? 
I`m sure the final result will not disappoint us - humble mortals 
Filip, the kit is excellent. Surely it is not a WNW kit, it is a resin model, with all the vices of this material. But when you remove and clean the parts, fill some air bubbles, work a little with files, sand paper, etc, the fit is ALMOST as good as with WNW. And the detail level in many areas exceeds that of WNW - the advantage of the resin enhanced with an extensive PE range.
And here is a report from further progress. The cabane struts, the engine, the air intake, the front bracing of the fuse, the rear turtledeck and the tail all basically completed. So is the interruptor gear, which will be covered by the cowl. But it was such a fine work of passion from Aviattic that I just could not resist including it in my model. I still plan to add the throttle linkage, maybe a fuel line and some water pipes over the timing gear shaft and under the engine crankcase - these after the radiator is mounted.





The top cowling and the fuel tank


The under cowlings

And the undercarriage which will have to be attached before I will start decalling the fuselage with wood.
The axle and its cover required some repair (air bubbles and missing material) and still need some sanding.
