I have one that I took apart to replace the LED with a neutral one, but never got around to it. I'm out of town, but I'll get you some info Sunday or Monday.
Excuse the dust and dirt, I took some of the dust off the body, but there is some on various parts of this. I scratched up the head with my strap wrench trying to figure out how I was going to get into the head. The body is in very good shape, the head is scratched up and has the LED removed and was waiting for a couple of years for me to put a new LED in it. It would make a good "For Parts" light in case you break the lens or something.
