I received the KAM i2's last night.
I've attached photos of the internals.
These bodies are about a 1/2 inch longer than the CAD GXL-1200 bodies. The KAM mics have the low cut and -10db pad switches on them. Also, the ceramic capacitors are green and all of the components match perfectly between the microphones. There is what I assume to be a quality control sticker on each mic circuit board.
The circuit boards look much better and there is no residual flux on them as there was with the CAD mics.
The electrolytic capacitors are smaller in size (physically) than the caps in the CAD mics too. This will make them easier to modify.
I did do some tests on them and they match pretty well.
I bought these on eBay, as B-stock mics because of the paint job. The flat black paint is already flaking away from the holes where the switches are. I'll probably sand down the tubes, install jumpers in place of the switches, fill the switch holes and re-paint them. As I don't have any use for the switches.
Also note that one of the XLR ends is brass and the other is (pot metal?). Also, the painted markings on each mic are slightly different, which may mean that they came from different production batches.
Overall, I think these will be much easier to work on than the CAD mics, because of the longer body and smaller electrolytic capacitors.
