Steven... thanks a ton! I think you've solved the mystery. What was in the documents you scanned is clearly my rack... so it's definitely an H967.
But if you look at the handbook link I posted earlier, it ALSO lists an H967, which is clearly different than mine and the document you scanned (ie. Fan sits in center of cabinet pointed downward with a cowling, and the top of the rack is flat, not sloped). So it would appear that over time there were two very similar, but different racks - both designated H967. Thanks! J
