I've noticed that, very often, when someone is selling a S&W revolver with the IL, they will photograph it in such a way as to try to hide the IL behind the cylinder release thumbpiece.
Here's an example:
I see it so frequently, I've come to think of it as "the myspace angle" of revolver photography. MySpace Angles | Know Your Meme
I post this not to bash the IL. I just find it annoying that people selling a gun go to such lengths to make it difficult to tell whether what they're selling has it or not. Obviously, if it's going to turn off some buyers, hiding it isn't going to help -- it's only going to waste both the seller and the otherwise-interested buyer's time. So why do people do this? If it has the IL, don't be ashamed of it, and don't try to hide it behind the thumbpiece.
/end rant.
