Dear Justin, Andy and Ernie, thank you for getting back so quickly.
Your photos are much appreciated Justin, but alas, neither one captures the A.II version I'm after. The main difference is that the Copper State Model features two pairs of undercarriage wheels; additionally, the model has no, what I take to be, port fuselage-side exhaust panels. Even so, thanks for searching.
Thanks for the offer of help, Andy, and I will certainly have many questions! The version of the model I have has seen the white metal parts replaced by resin. Hopefully that will have solved the propellor problem you mention, but brings other issues in its wake. Unfortunately, the book you mention is way beyond my means going by Amazon prices.
Thank you for you kind words, Ernie. I will certainly post a build log, if only to record my problems. I bet someone like WNW will release a Taube before I finish!
Best wishes
Nigel
