Thanks a lot, Dan San Abbott. And for the other useful posts to the Hannoverana-topic in the past. It took me quite a while to search this whole forum.
First of all - it will be the 1/72 Airfix kit, user "blimp" let it to me. With Pegasus' 1/72-Lozenge-Decals.
In my opinion the kit is a good base, worth detailing. I don't know if it matches the original 100%. The Windsock Datafile #23 ist temporarely not availlable in Germany, so the internet ist my source. There i found the linked thread of the dutch modeller, which ist useful for me, although I can't read dutch.
The polygons on the fuselage are said to be irregular. I don't believe they are field applied (free hand painted). But was there a spray-mask used? Continuity? I believe to see regular parts (like immitated chords of fabric).
This time a have to scrap the lozenge from the plywood-covered center part of the upper wing. I was too fast, too enthusiastic.
Thansk for the metuen-code. I will google for it's FS or RAL standart, other colors aren't at my stock. If there aren't any - mixing. I think a proper match to Pegasus will to the job.
Aren't the wheels fabric-covered?
So interior clear plywood, this will be the start of the fuselage. I will open a thread at Modelling. It don't want to bother the non-modellers with my questions here. Feel free to post there.
