That is the ST90 Search & Rescue. Here is a link to the thread on this flashlight, here in this forum:
Presently, I only offer this flashlight as a custom hand made, as I ran out of stock of the CNC machined parts. This flashlight was so costly to produce them, I cannot afford another big run of them, but, I can make them one at a time.
See my web site and links to the web page for this flashlight. I also have a youtube channel, here’s a link to one of the slide shows I did for this flashlight: http://www.youtube.com/watch?v=fh_R0g0F0Ok . I need to go into my Youtube channel, they changed things around.
