Okay, we're all familiar with the Kelley Blue Book. I imagine some of us know about knockoffs, like the Camera and Lens Blue Book, or the Firearms Blue Book, or on the same lines, the Standard Catalog of Firearms.

I, however, don't currently have the money to spend thirty-five bucks a year on something vaguely pointless. If I did, I'd buy a team membership here.

Is there an equivalent of the Standard Catalog of Firearms based online, for free, like www.kbb.com for cars?

So... nobody knows?
