Parker Hale 5C repair help requested

[slug]

A friend has a later model PH 5C and he has suddenly lost the click ability for windage adjustment.

If you press the windage knob firmly to the left, you can make adjustments but not firmly.

If you know of a fix, please chime in.

TIA.

sounds like the tiny ball bearing or spring that holds tension on the adjusting knob may have gone missing?

Or could have possibly been pushed down and seized in that position due to dirt or rust. Would have to be taken apart to find out for sure.

The plate is loose and the ball and or the spring is missing.
