Hi.
The first row of pictures on the "MK" website show the stalks I've also found advertised on the website of the Austrian Importer. Second row is the "Morgan Park" type.
More information about the "Merz & Papst" column stalks can be found in their news section of their homepage (
http://morgan.merz-pabst.com/news.php) - you've got to click almost through the entire news section, but you'll be rewarded with prices (hold your breath) and a nice brochure (downloadable PDF).
These stalks incorporate the intermittent wiper funktion - no secondary switch is needed.
