And this one has a collar and big nut, which is what mine came with.

I think that the collar I have actually belongs between toolpost and
ridged plate, and that the top collar is missing. Although they could
be identical. The collar I have is beat up and may be slightly oversize
for the top position, and interferes with the wrench at some some holder
clamp positions.

The shoulder washer for the top of mine has similar effects. I
think that it is intended to prevent the cam for the T-stud from
rotating too far in the open direction.

In mine, the T-stud cam hits the raised pedestal upon which the collar
rests. This pedestal is an integral part of the toolpost body.

In which case, it is an intentional interference to prevent
rotating the cam too far and perhaps making it more difficult to slide
the tool holder into place.

I may make the top collar a bit smaller, to prevent interference with
wrenches.

With the wrenches, or with the locking flanges on the cam shaft?

Note that this is one of the advantages to the Aloris style
toolposts. You don't have a detachable (and losable) wrench, but
rather a rotating collar around the raised part which the nut tightens
onto to lock the toolpost into place. (Of course, if you have a hinged
shield to keep the chips out of the operator's eyes, as on the
Compact-5/CNC, the removable wrench means that the shield does not need
to be as large.)

Enjoy,
DoN.
