It looks like a real monster, and that stainless frame certainly is unique.
The ad at the bottom of the article is interesting. One of my father's best friends test road for ATK for a long time through the 90's (and even tested for Cannondale before they fell apart), the last I heard he still owned something like 25 ATK's. I've had the opportunity to ride a few of them on various occasions, that rear brake always sucked if you ask me. I did like the rear suspension performance under braking, but braking power wasn't amazing and the heat can be felt through the boot after a while.
I never knew the Maico history with those, thanks for sharing.
