The spec most plating houses use for anodizing is MIL-8625F
Type II is your standard anodizing, or “clear coat”.
Type III is your hard anodizing, or “hard coat”.
I’d guess that it’s a type II, as type III will often give a duller color (but have the aforementioned benefit of hardness…better than tool steel).
As for the texture, the anodizing house i typically work with tells me that whatever the finish you haver on the raw metal is the finish you will have on the anodized part. For the jobs I’ve done that’s held true for brushed and bead blasted surfaces.
