Abrasive Blast call out

[JordonMusser]

I have an old (1979) drawing calling out a:
SPEC 13197 ABRASIVE BLAST TYPE 1

And I am trying to find a spec that is similar. Essentially we are sand blasting an aluminum (6061-t651) surface before we anodize it for reduced reflectivity in an optical system.
