Can someone help identify the brand of this 11x17 Large Format Camera?

The name is rubbed off on the front of the camera and I'm needing help identifying who made the camera. Actually, it might not be 11x17. I need to measure it. I don't know much about large format cameras so any help you guys can offer is greatly appreciated. Thank you guys in advance!

Gundlach Korona. Looks more like a 7x17 to me.

Yes, a Korona Panoramic as it looks very much like my Korona 8x20.

Measure the ground glass to determine which it is 7x17 or 8x20.
