Can anyone ID this clutch?

Hey guys. This clutch came on an engine I got in a package deal years ago. I finally put it on a bike the other day and am super impressed with it. Very smooth engagement with a decent launch. I can't find any info on it though. No markings, and I haven't found a picture of another one.

Does anyone know what it is so I can keep an eye out for another one?

Looks like a Mercury clutch. Should have the name on the face towards the engine.
Thanks Dick. I do see some similarities to the mercury clutches but I haven't found one that looks like this one. The only markings on the inside say "Max RPM-4000." No other markings that I can find inside or out.
