An earlier patent too refers to the same design:

Probably neither is the primary patent...

Because of curvature and which elements are ED only the earlier one is a possible fit.

So I added Example 3 to the optical bench enev though it isn't perfect.

That whole patent was a nuisance because it'd for several different designers with different styles of presenting the data.

I guess this isn't the primary patent for the 105mm ? But it is the best match I have found so far. There is an earlier one for 105mm f1.4 but that is clearly a different design.
