Just realized that this handlebar stem/eyebolt is not stock (neither is the M style bar [believe that is what that bar is called]). What type is this and is it from another bike or an aftermarket stem?

What is this particular part for?

'Dog Bone' handlebar riser?
. . . not too bad looking!

The bottom pic is of a handlebar clutch cable abutment- adjuster.

The small knurled and threaded part is a cable adjuster. It goes into the perch for the clutch or drum brake lever.

That set of risers looks more like something to give the bars some setback, making them closer to the rider. Probably aftermarket part.

OIF bikes for US market had buckhorn bars.
