I included it (3x18650 C-C) as an option in case they started making them... You're right, as of now, it doesn't exsist, but if it becomes available, the chart will be ready to go. I should probably put a note next to that however..
I'll have to check into the TB tubes and FM towers.... I'm not as "in-the-know" about the stuff that we aren't seeing offered through something like a reseller like lighthound. In my experience on CPF, I've found that if it only exists in a sales thread, then it's often a limited time offer, limited run, available 4 months out of the year, back-ordered 6 months, etc etc etc.
as far as your original question goes... I dug up an old thread earlier today. And found reports of compatibility between G&P and surefire "C" style threads. G&P makes a mini-turbo head. The lamps are the same as the G90, G120, G60, etc... but the lamp screws into the larger reflector, the head assembly should theoretically screw onto a surefire flashlight.. but I still don't think it will support a 36mm reflector module...
