Disco 1 found in swivel seal landing

I replaced the o\s front bearings several weeks ago and did a quicky (read sloppy) replace of swivel seal
by nipping the new seal and cleaning the landing and rtv'g it in. while cleaning the landing I hooked this out.

I have looked at several good videos and exploded assembly pictures and can't figure out what it is.
it is both too small and insubstantial to be part of the needle-bearing.
Another Landy enthusiast and professional mechanic looked at it and said it might be a cir-clip from the axle but his certainty level was pretty low. Any ideas mates?

is there not a spring ring as part of the CV joint retainer?

Cheers

I had a real bitch of a time getting the flange end cir-clip back on when I initially found the sloppy bearing and attempted to snug it up, it went on a lot easier after I replaced them.
I had read the flange bolts are supposed to fit the threading in the axle, but that wasn't the case for me.

iirc , I normally use an M8 or M10, it does not screw in, just hold it at an angle and pull the halfshaft, the circlip just pops into place then.

Ta Neilly. That is indeed what I did. I bet it is an imperial thread.
