Zenith chassis nubers usually are two numbers, 1-2 letters, and then two more numbers and some times a post fix letter(ie. 16C21). Zenith tends to put the chassis number on a sticker on the side of the HV cage that faces you when you pull the back off.

It's supposed to be a 17D20 chassis.
Oh look! Here's a picture of the front of the Photofact in an eBay auction, and it has a knob like mine!

I definitely think my set has the correct knob.
