Rb26 cam identification

[Griffin]

Does anybody know if aftermarket cams are branded? I've had the covers off and only marking I can find is the one pictured. It says 64 and 9.0

Would this be 264° and 9.0mm lift? Assuming it's  stamped 64 and not 264 as it obviously can't be 164 or 364° 

Any ideas?

Not that it looks to be a Tomei cam, but possibly, maybe even probably. 

You can measure the thing as follows:

 

LOBE HEIGHT

Machining each lobe to the strictest tolerances allows for smoother and more precise adjustments in valve clearances. Based on: 9.15mm max lift, Φ32 base circle SPEC. 41.15mm ACTUAL (avg.) 41.1455mm DIFFERENCE (avg.) 0.0045mm DIFFERENCE (%) 0.0001% The greater this 'difference', the more shims and time required to adjust the valve clearance.
