Hub and cone mismatch

Folks,
a pal of mine just swapped a few of motors around, but swapped hubs to keep paint matching.
He went out on one of them which is a pretty quick motor and found a wobble after about 20 miles, luckily, no fall or anything.
He showed me the evidence inside the hub on a photo and i suspect that he has mixed the cones up and he now has an 8° cone in an early 11° hub. And he has sold the other one with the opposite mismatch. There's another motor involved somehow, but I'm not dead sure how; all a bit confusing.
This is all suspicion as I've never actually held the parts, just photos (lockdown makes life tricky).
The part number inside the hub is 19945100, but i cant find this using google or the parts lists I have. Does anyone know what hub this is?

This is the 11 degree hub as fitted to all series 3 machines

I thought later s3 and all gp were 8 degrees?
Regardless, that confirms part of my suspicion. I think he has a later 8 degree cone from a bike I sold him.

Only ever seen 8 degree cones on engines with GP shoes and GP brake cams myself.
There may have been some crossover?

After some advice, I have a remade rear hub, 19-54-5120. (FFI)2. P. 1223: these are all the numbers on the inside, I was hopping to repaint and reuse on my next project question is what pitch would the cone be as the fool I am I’ve lost the 1 that I had with it?
Cheers Shane.

Probably easiest to take it in to your nearest reputable dealer who should be able to sort that for you.

It turns out it’s a FA Italia hub when I look at it properly. FnF all shops are shut are they not?
Cheers Shane.

I have had the same problem. I have a hub with the same part number it's a later type with no recess and double lip around brake liner.. been looking online and it says 8 degree cone so I'm a bit lost on which to buy now.
