Surface finish for IMP parts

I ran into an old print for an injection molded plastic part that specifies an SPI No.6 finish for the surface. I would like to know where I can find a complete list of specifications for surface finishes on IMP parts that includes the one mentioned earlier.

There is no better source than the person who signed the print.

Same question: do you know if any on-line tables/lists/examples of mt and spi finish specs?

Thanks,
