Clutch identity?

Can anyone tell, with only this minor visual data, what AP clutch - relative stiffness of release - this might be? I'm having trouble with the mechanical components but want to find out about the clutch as well as it seems really, really stiff (like impossible to disengage stiff). Yes, I should have cataloged this before I put it together and will do so when I pull it back apart over the next weekend or two, but thought maybe someone would recognize it.

Thanks,
Dave
