I think you will find K&C has a research Dept.
I am guessing they spend thousands of hours researching every vehicle and sending their technical people to all the relevant museums and personal collections to count the rivets and measure the various bits. In addition they have a team of people who read every book and magazine published about armour and uniforms and have a researcher in every military museum in the world. They of course have acesss to all the records for every vehicle ever made in WWII and what colour it was on every day of the war.
Actually I think I could be wrong as that seem like it would slow things down and increase costs considerably (in fact I recall with much amusement reading a thread with many posts by obviously well read forum members about Wittmans Tiger and by the end of it I was none the wiser as to what would be correct).
I think somebody called Andy could be the research Dept and he seems to be quite overworked as he also has to worry about Jesus (I recall the post quoting the bible and noting the stables were wrong !!), Egypt, Medieval, Naps, American Revolution, American Civil War ( one poster pretty much said all ACW figures available from all brands were wrong except some recent Britains that were good only for Gettysburg !!), Alamo, Crimean, Empire, WWI, RAF, US Air Force, USMC, US Navy and mutiple items for WWII. Current range is probably in excess of 1,000 items.
If the Elephant does not fit in with your knowledge of the Battle of the Bulge then do not buy it. If you want toi display it being attacked by Crocket, Caesar and Cornwallis then go head as what you do in your own home is up to you. You command the troops you buy.
I have had minor disagreements with the Research Dept and I would have to confess the WWI German armoured car was one of them. However I would have to say that if you were looking for a one man research Dept then the guy for the job would have to be called Andy. Even more so when it is his own money.
LONG LIVE THE RESEARCH DEPARTMENT

That is my totally unbiased humble opinion.
