This is my S14 crank, I know it's forged to give you an idea. Did they make forged M10 cranks? Or are you wondering if it's a S14 crank? If so this picture should answer your question.

I'm no expert, but just based on that photo, I would say that is cast. You can see the shaved off casting marks, plus the ends of the counters are quite rounded rather than the squared off edges you would most likely have on a forged piece
