Rotors available (for now) for K-H disc brake cars

If you have any pictures of your original rotors I'd love to see them. You mentioned the original hat was rough cast (not machined), but how was the original hat shaped; cone, cylindrical, or stepped?
Slight taper to the hat. I should be able to dig out a used rotor this weekend.
Here's a few digital photos off my computer

Search saves me from digging through my files for the rotors that I had to return to NAPA in 1992.
Bendix PRT 1054.
The hat casting was egg or cam shaped. Only hit the piston boots once each rotation.
