I've never carried this one "in anger", but it was heavily used and has a great story from the previous owner. Mind you, the light should be 100% jet black.
"I bought that light in the seventies while I was an MP in
Germany. When I started at xxxxx PD in 1978 they didn't provide
flashlights at all as part of issue so they allowed us to carry whatever we
bought. In 1981 I was riding shotgun on PM shift when our unit became
involved in a chase headed toward the xx border on Interstate xx. The
suspect driver was DWI, suspended and had a couple of bench warrants out for
him and he kept trying to force other vehicles into our cruiser. My Partner,
Officer xxxxxxx, brought the cruiser up alongside the suspect and I reached
out and tried to hinder his vision (mind you we were doing 85-95 Mph on a
bridge) by smashing his windshield with my flashlight. Well, I lost my grip,
the light bounced off the suspect's door column and was last seen skidding
under an 18-wheeler that we'd just past. After making the arrest at the end
of the chase in a field in xx we went back and found that light against the
curbing at the top of the bridge. The light survived pretty much intact. It
had a few good scuff marks on it, but I put a replacement bulb in and to my
amazement it still worked. I carried it until about 1985 when the PD started
putting rechargable lights in the cars."
