Thank you for your overwhelmingly kind comments. Yet, I wish to stress, that every possible praise should go to Lukasz. I only played a role of an assembler.
I have mixed feelings about it not fitting into the cowl. On one hand, it would be nice to be able to have a complete airplane with the cowl in place, but on the other hand, it would be a shame to hide that beautiful engine..

My thoughts, exactly, George. A hard choice had to be made here. Snipe has such a charming nose (beak

), but my model will not show it.

If the cowling has to be thinned that much would you consider using it as a master and plunge a new one from heated plastic sheet?
That would be an option, but heat-forming is well beyond my skills and possibilities.
Given the engine is more or less 90% hidden by the cowling have you considered the Kit engine installed with the Taurus Bentley displayed beside the model?
Cheers,

I am not for dioramas, even at the slightest, Lance. What I do at the most is some basic base, and this only for floatplanes which must have a landing gear not to look weird. But thanks for your suggestion.

And after all, there would be enough of WNW Bentley visible to notice that it is clunky when compared to Taurus one.
When buying Lukasz's engine I was sure I wanted to install it in this model. The fact, that the cowling is too large, made my decision easier to expose it completely. Otherwise, I would be torn in two, between the great engine and nice Snipe beak.
So, the model will have no cowling and no propeller, they may just be somewhere at the side, propped against the undercarriage, or so. Will think of it, yet.
