Thank you, everyone.
Well, now the build goes in two parallel paths. For path one - the fuselage is closed, the seams filled with liquid CA glue, now curing before sanding and smoothing starts.
For path two - not to waste time, I have turned my attention to the Liberty engine. First of all I have realized that the war version of WNW Ninak instruction has two pages of excellent reference photos not included in the post-war version. But the most important thing is that I found the treasure here, in the Des' website - His masterful enhancement of the WNW Liberty engine. I will try to follow his steps as well as my skills allow. So I have
i) cut the gaps between cylinders,
ii) prepared small priming cups (some spare resin bits with fine 2mm rods ready to drill the holes and install the soldering wire bits as valves),
iii) drilled the holes in the top intake manifolds to for them
iv) decided not to exchange the spark plugs aware that my possible replacements would not necessarily be any enhancements
v) corrected the electric wire lead - WNW prepared the holes for 24 cables on the upper side and omitted the holes at the front for two front spark cables as well as the inlet at the rear where the cables from the magnetos enter the lead.
