Where can I find a laser mount for a tiny rail?

I picked up one of those tiny derringers for the hell of it, but now I'm curious what kind of accuracy I can actually get out of this, so I'd like to mount a laser sight to it. Or maybe a scope. But that'd be just for laughs, followed by jaw drops at the range. It's double barreled, chambered in .22LR, but I plan on buying a .25 or .32 barrel for it.

Here's the gun:

So there's a rib running along the top. I measure it at about 5/32" wide (I don't have my calipers to check the narrow parts). A laser sight that clamps on this would be ideal.

My other option is to get a laser bore sight. That'd require one of the other sizes, and use up one of my barrels, so that's more of a plan B.

Any other ideas, or anyone know where I can find a laser sight that'll clamp on that tight?

You could try a 3/8" mount, though the rib is 1/32" smaller. You might have to remove a bit of material from the mount so that it will close more tightly and hence be able to grip the 5/32" rail, likely AFTER you remove some metal for the mount to grip the rib/rail, or from the mount, as I doubt you will find a mount that will just fit the cutouts only.
