Google Image search might work.

It doesn't, although it did produce an interesting door lever shaped like an alligator.

I know I have seen this knob quite recently. It was a thread about new knobs for a mid-century dresser, and one reply had pictures of several different groups of knobs, one of which may have been this one. Does anyone remember that thread? I can't find it again.

ETA Nope, that wasn't it. The one I was thinking of was the emtek Tuscany knob, which isn't quite the same, more petally.

If you want to try google image search, take a more straight on picture of one, on as neutral a background as possible.

Maybe it is time to change them ALL ? Fifteen years is a lifetime in hardware.

I agree liva a little change is good for the soul.
