Thanks, Frank, Guy and Stephen.
Well, Guy, I can only confirm, double builds lead to problems for me, too. It seems I somehow cannot focus properly on a model, rather I am thinking of the other one instead of working quietly on the one in front of me. And I seem to forget about some details or make wrong decisions - the one with windscreens. Not any more!
Stephen, first of all, it is not my intent to put anybody to shame. But I can stop showing my models at any time, just let me know
Secondly, you should not tell things like this, we all know your great scratch builds! So, do some sewing, if you like, but do not do it instead of modelling, please!
