You really can't change it to look that way?

You would save a lot of time avoiding the sharp corners where the
partial ring joins the cylindrical part. You also avoid a lot of nasty
precise setup if there is a bit of land left between that what you
intend to mill away and the cylinder.

How's the pin oriented? parallel to the cylinder's axis?

You also could turn rings on your lathe, mill off the 90°, part off
"shims" with a circular saw (in the mill) and brace that 270° ring to a
plain cylinder. Least work, I guess.
