No such thing as a perfect kit, as someone, somewhere, will always want more !
There are kits which are extremely good, being accurate, and with some nice detail, and some of these are not new either. But the average modeller today expects this and that, and will complain that this part isn't right or that bit isn't included, or it hasn't got ready made and painted whatsits!
Let's face it, there are even aftermarket detail sets for even the most accurate and detailed kits only just released !
There are limitations to what can be achieved in injection moulding, and more so if the retail price is to be kept within reasonable limits (whatever they are these days !), but in the case of the Hasegawa 1/32nd scale Bf109E, people shouldn't really complain, as this kit is over forty years old, originally designed and tooled before Hasegawa were even heard of, and way ahead of it's time back then - a time when the average modeller was happy to get something which was fairly close to resembling what it was supposed to be ! Being fair, if built straight from the box, and well finished, this kit would pass cursory inspection, and 'Joe public' wouldn't know the difference anyhow. I certainly won't be going down the route of accuracy to the nearest half millimetre, not even close - just getting it to look right, as opposed to being 100% accurate!
EDIT: Crossing posts. Thanks for the profile Wojtek. I notice the III Gruppe 'welle' is shown, which was still being used by a few units, although Wubke's aircraft had the fuselage cross further forward than normal, and didn't have any III Gruppe marking, which was true of more than one aircraft from the Gruppe apparently.
