Real Masterpieces?

A couple of weeks ago I was following an auction on eBay (where else? ). The item to be auctioned was a spare parts list for a Kübelwagen from 1943. It was in perfect condition. Maybe a bit too perfect, so the first thing that went through my mind was, “Is it Real?” Also the seller could not confirm whether it was original or just a cheap reproduction. If it was original it definitely went cheap and the winner is very lucky. Normally the original ones go for hunderds of euro’s. I didn’t bid on it as the chances are high of buying repro stuff on eBay these days.

Also the following piece of KdF literature looks repro to me but I’m not 100% sure. It’s some sort of repair manual for a Kübelwagen from 1940 sold on eBay. Can anyone confirm if these items are original or not?
