Skipford Van Beaverhausen (Skippy for short or Dave Simanoff of The Daily Dave fame) has informed me that the .tk at the ending of the Knupke web site stands for the Tokelau territory of New Zealand. So there is some Knupke out in the Pacific Ocean writing about classic military vehicles in German.
Whew! I got tired just typing that in.
I must e-mail this person..anyone write German?
