I had these parts made for a project I am working on and the manufacturer claims they are 'autoclave dry carbon', which should mean pre-preg, but to my untrained eye it looks like regular vacuum bagged wet infusion. There are tiny bubbles along the edges and the outer clear resin layer seems thicker than what I would expect a pre-preg.

Are there any carbon experts out there that can help me identify what process they used to make these parts?

       

I would say it doesn't matter way process is used. What matters is if you are pleased with the parts or not. Optically and physically.
However, watching the perfectly straight diagonals  I would absolutely believe that these parts are made from prepreg. It is difficult to keep perfect straight fibres with wet layup/vacuum compression.
If your  manufacturer got an autoclave he would be really stupid not to use prepregs anyway. In total the additional labour for wet layup outweighs the higher material cost and outoclave operating costs.
To be relatively sure, you could heat the parts up to 120°C and look it the become flexible. No standard laminating resin could take that temperature, but almost all autoclave resins can.
