Do only 6P and newer have a model stamped on the tail cap? Mine has the etching on the back of the tail cap, as opposed to around the circumference, but no model number. I think that I'm too new to post a picture.
Bought a 9z off ebay in really nice condition, looks hardly used. Wondering if it's been partly legoed over the years , the body and bezel seem true to the era .. but the tailcap looks newer , it doesn't say laser products . It has a side dimple and internal hex screw and says surefire.com. surefire USA.
What year, does anyone know, did surefire start using the website ? The head is smooth also which doesn't fit with what I looked at on the first page here, the closest year available , 1996, catalog appears that it was supplied with a striped knurling on the bezel vs completely smooth like the one I found. I bet someone who was into collecting these every year back then could really shed some light on the subject.
