I would think quality control at any toy soldier factory has to be a bit of a misnomer. Rob, you have been fortunate that you have not had any broken items and, not detracting from the service K&C UK offer as it is first class I don't think, the factory or, K&C or, many dealers have time to look at every single item and check after a delivery to see that everything is in order. particularly to look to see if a barral is lower than it should be. some may not even realise this is actually a problem if they saw it.
Remember the Flak 41 it went from completely broken to slightly to minor damage to none at all. If everyone was checking then this would never have got out of the factory or, to the collectors door. Some even got exchange after exchange that were broken.
You are just as likely to get a barral drooping from K&C HK, UK, or the guy that sells on ebay. Some have this some don't. what this thread shows (probably not how it was hoped) is its not the everyday occurance that some have stated.
I have been buying K&C and, in that time have only seen or had through my hands three items two of which were broken and one had a thumb print on a flag. I think in relation to K&C thats not bad going considering what I have bought.
