LED old flashlight identification

My friend has this lantern. It was given to him by a German about 10 years ago. It's clearly custom. Battery 16340, but there is a chance that 18350 can also fit there. Someone was inspired by SF 3P

Has anyone come across this design before?

Looks like a custom light, milled to spec.

Yeah, a friend sent me a couple more photos, the back cap is very indicative, the same one was on my MAC and I don't remember anyone else using these black plastic threaded rings with holes

I dug up a photo of my old tri-edc. The plastic ring with holes, cap and back end machining radii are very similar

XM-L 18350

Perhaps this is it, but even in the Internet archive there is no photo left...

Either this is something from the P60 series, but there is also no photo preserved
