Which way around, upside or downside?

Hi
I’m putting my reinforced and repainted 3CL frame together but is confused by the direction of the lowest shim/washer that goes under the tapered roller in the steering head. Which side is up? I cannot find any detailed picture and the old one was flat. So should it be A or B ? My best guess is A but really have no idea and the pictures I seen at various sources are not clear.

That looks like the cap which sits on top of the top bearing, below the top yoke, to keep the clart out of the bearings.

No, it keeps the muck out of the bottom bearing, concave side up.
You can clearly see the cupped washer in this pic from the 500 workshop manual.

Correct - A

Intended to shield the bearing from crap/water

Thanks, very useful info. Once the bearing is on I will have very little room for regrets. This bike had none of the caps installed so its time to get the steering head back to as it was intended. Not sure if that will cure the slightly nervous front end but there’s hope.

Just did mine on the 120 jota, I add an o ring in there to make a perfect seal to keep the dirt out.
Nervous front end usually caused by the rear end......
