Wow FAAMAN, You're really into the A4!
I remember I went through a similar phase when none of the kits being produced of my favourite subject (P-51D ) were accurate enough with the result that I ended up never building one for years!
Then I attended a work seminar during which the speaker asked us what was our Architectural Practice there for. We all went on about the quality of buildings etc etc. He said WRONG. Your Practice exists for one thing. Profit. If you don't make a profit your firm will go under and pop go all your good intentions.
I realised then that the same thing applies to models. A manufacturer can only devote a limited number of hours to research if he ever hopes to realise a profit. He must make sure that his product is good .... indeed good enough to satisfy 90% of his clients to achieve enough sales to generate a profit that will allow him to continue in business.
The truth is he will never ever satisfy the last 10% no matter how hard he tries and how much time (and money) he spends trying to do this.
And that is where model making as opposed to kit building comes in. One takes the bare kit and corrects the faults one sees in it.
Don't get me wrong ..... it would be great if all kits were manufactured to be perfect replicas. Realistically speaking though this is impossible and would result in kits being so expensive that no one could ever afford to buy them.
Have you thought of writing to the author of that article and discussing the matter with him? I've done that in the past with other articles and found the authors only too happy to discuss the issues.
