Anyone got an idea as to what she is? I googled a bunch of things and came up empty? Nothing on "Standard" or "original Standard" and I don't get the "K" head badge either.
I think it's German. You get more hits searching fahrrad. I'm not sure if "Original Standard" is the maker, or if its a badge name and the bikes were made by different manufactures. Some seem to have been manufactured in Bielefeld, Germany. That should give you enough info for more in depth research.
